Full textAbstract:
Organizational autonomy of the interuniversity athletic department, university responsibility for athletics, and pressure from nonuniversity individuals, groups, and organizations are all concerns related to the department's dependence on various sources in its environment for financial support. The Emerson (1962) power-dependence theory of social exchange relations, and its adaptation to the study of organization-environment relations (Pfeffer & Salancik, 1978; Thompson, 1967), guided an examination of funding and control in Canadian university athletics. This study examined whether athletic departments are perceived to be controlled by the funding sources in their environment according to their relative resource dependence upon those sources. Financial resource dependence and perceived control data were obtained from athletic directors (ADs) at 34 Canadian universities. Significant Spearman rank order correlations reveal the resource dependence-based perceived control of the university central administration, corporate sponsors, and provincial/federal sport organizations and ministries (p< .05). Of these, however, only central administration was perceived to have considerable control over the departments. Nevertheless, ADs should be aware of the resource dependence-based control potential of these other sources.

Abstract Objective The objective of this project was to enable poison control center (PCC) participation in standards-based health information exchange (HIE). Previously, PCC participation was not possible due to software noncompliance with HIE standards, lack of informatics infrastructure, and the need to integrate HIE processes into workflow. Materials and Methods We adapted the Health Level Seven Consolidated Clinical Document Architecture (C-CDA) consultation note for the PCC use case. We used rapid prototyping to determine requirements for an HIE dashboard for use by PCCs and developed software called SNOWHITE that enables poison center HIE in tandem with a poisoning information system. Results We successfully implemented the process and software at the PCC and began sending outbound C-CDAs from the Utah PCC on February 15, 2017; we began receiving inbound C-CDAs on October 30, 2018. Discussion With the creation of SNOWHITE and initiation of an HIE process for sending outgoing C-CDA consultation notes from the Utah Poison Control Center, we accomplished the first participation of PCCs in standards-based HIE in the US. We faced several challenges that are also likely to be present at PCCs in other states, including the lack of a robust set of patient identifiers to support automated patient identity matching, challenges in emergency department computerized workflow integration, and the need to build HIE software for PCCs. Conclusion As a multi-disciplinary, multi-organizational team, we successfully developed both a process and the informatics tools necessary to enable PCC participation in standards-based HIE and implemented the process at the Utah PCC.

Professor Susumu Hara is based at the Department of Aerospace Engineering, Nagoya University in Japan explains that when the Mars rover Opportunity was set to land on that planet in the first weeks of 2004, onlookers held their breath as it dropped from orbit and hurtled toward the red surface. 'Any failure in the calculations or landing systems would mean a harder than expected impact,' he highlights. 'The impacts sustained by a rover such as Opportunity can derail a mission before it even starts, damaging cargo or vital systems required to complete the mission.' Impacts occur during landing but also as the craft enters the atmosphere, when it makes sudden moves, while it is on surface or when debris strikes it. 'Therefore, a system and materials to protect a craft are vital,' outlines Hara. 'Surprisingly, the solutions to this problem are not sophisticated. In fact, most craft still employ devices resembling automobile bumpers, which absorb the energy from an impact by crumpling under the force of said impact.' Unfortunately, these cannot be reused, even during testing phases a new prototype is required after every single test run. Recent missions also employed techniques like airbags or sky cranes. While successful they too have drawbacks. 'Airbags create huge rebounds which can jostle the craft and the contents inside while sky cranes are extremely costly to develop,' Hara says. For this reason, he is dedicated to designing a new highly reliable and cost-effective shock control mechanism.

AbstractObjective:A computer virus outbreak was recognized, verified, defined, investigated, and controlled using an infection control approach. The pathogenesis and epidemiology of computer virus infection are reviewed.Design:Case-control study.Setting:Pharmacy of a tertiary care teaching institution.Results:On October 28, 1991, 2 personal computers in the drug information center manifested symptoms consistent with the “Jerusalem” virus infection. The same day, a departmental personal computer began playing ‘Yankee Doodle,” a sign of “Doodle” virus infection. An investigation of all departmental personal computers identified the “Stoned” virus in an additional personal computer. Controls were functioning virus-free personal computers within the department. Cases were associated with users who brought diskettes from outside the department (5/5 cases versus 5/13 controls, p = .04) and with College of Pharmacy student users (3/5 cases versus 0/13 controls, p = .012). The detection of a virus-infected diskette or personal computer was associated with the number of 5 1/4-inch diskettes in the files of personal computers, a surrogate for rate of media exchange (mean= 17.4 versus 152.5, p = .018, Wilcoxon rank sum test). After education of departmental personal computer users regarding appropriate computer hygiene and installation of virus protection software, no further spread of personal computer viruses occurred, although 2 additional Stoned-infected and 1 Jerusalem-infected diskettes were detected.Conclusions:We recommend that virus detection software be installed on personal computers where the interchange of diskettes among computers is necessary, that write-protect tabs be placed on all program master diskettes and data diskettes where data are being read and not written, that in the event of a computer virus outbreak, all available diskettes be quarantined and scanned by virus detection software, and to facilitate quarantine and scanning in an outbreak, that diskettes be stored in organized files.

Abstract Introduction This study examined risk factors for secondary traumatic stress (STS) in behavioral health clinicians and whether access to the Post-Traumatic Stress Disorder (PTSD) Clinicians Exchange website mitigated STS risk. Methods A diverse sample of clinicians (N = 605) treating traumatized military populations in Department of Veterans Affairs (VA), Department of Defense, and community practice settings were randomized to a newsletter-only control group or the exchange group. The exchange website included resources for treating PTSD and promoting clinician well-being. Online surveys were administered at 0-, 6-, and 12-months postrandomization. Regression analyses were used to examine the link among risk factors, exchange access, and STS. Results Baseline clinician demographics, experience, total caseload, appeal of evidence-based practices (EBPs), and likelihood of adopting EBPs if required were not linked with STS at the 12-month assessment period. Providing care at the VA, more burnout, less compassion satisfaction, greater trauma caseload, less openness to new EBPs, and greater divergence from EBP procedures were linked with greater STS. Only burnout and divergence were associated with STS after accounting for other significant STS risk factors. Exchange and control group clinicians reported similar STS levels after accounting for burnout and divergence. Conclusions Given that burnout was linked with STS, future intervention may use techniques targeting burnout and STS (eg, emotion regulation strategies). Research exploring the link between divergence from EBPs and STS may inform EBP dissemination efforts and STS interventions. Finally, results highlight the need for research optimizing STS intervention efficacy among clinicians treating military populations.

Full textAbstract:
Activity-based costing (ABC) is a method where the costing of the product or service produced is performed on the basis of the activities. This method provides advantages to healthcare managers such as more realistic cost information, elimination of indirect, unnecessary and time-consuming activities and performance measurement. The aim of this study is to examine the applicability of ABC method in health institutions and to compare the calculated costs with the HIN price list. With this aim, the costs of the procedure of IVF center in a university hospital were calculated with the ABC method. Cost calculations for the procedures of Oocyte Pick-Up (OPU), Testicular Sperm Extraction (TESE), Embryo Transfer (ET) and Microinjection as discussed in the study were made with the ABC method and compared against the Healthcare Implementation Notification (HIN) system price lists. The calculated costs were determined according to the effective exchange rate of the dollar. It was revealed that the calculated costs differed from the price list. Finally, the findings suggest that ABC method could provide significant benefit for healthcare managers not only for to understand actual care costs but also to improving the cost control efforts as well as to planning the profitability analysis for hospitals. ABC method would provide a better opportunity and competitive for hospital managers to make a more accurate comparison between their and other health institutions.

Full textAbstract:
This study examined the characteristics of internal accounting control system based on size of human resources assigned to the system to verify whether downward stickiness of total cost and selling and administrative expenses differentially appears according to the level.An entrepreneur who wishes to maximize one's utility has an incentive to externally grow the enterprise beyond the optimal size or to possess idle resources, creating cost sticking phenomenon by possessing surplus resources even when sales volume decreases. Previous studies verified the effect of control system intended to resolve the agency problem on asymmetry of cost. This study expanded the scope of previous studies to consider internal accounting control system as a monitor of the agency problem. Enterprises that effectively operate internal accounting control system are expected to show limited opportunistic incentive of the entrepreneurs because of reduced agency cost.The main purpose for enterprises to establish and operate internal accounting control system is to provide accurate and reliable financial information to investors by preventing or uncovering accounting scandals of the management and possibility of errors. Internal accounting control system of Korea was first introduced in September 2001 through 'Corporate Restructuring Promotion Act', and Financial Supervisory Service announced the regulation on public announcement in September 2002 as a series of relevant measures. The regulation requires enterprises to publicly announce the number of workers in each department in charge of internal accounting control system on the internal accounting control system report. Under the presumption that internal accounting control can be more effectively done by increasing the number of workers in charge of internal accounting control system, the intent of such public announcement is to provide external interested parties with information that can be used to determine whether internal accounting control system of an enterprise is being effectively managed. Accordingly in this study, enterprises with large size of human resources assigned to internal accounting control system were predicted to show relaxed downward stickiness of cost.As a result of verifying 2,532 enterprise-year samples listed on Korea Stock Exchange between 2003 and 2008, enterprises with larger size of human resources assigned to internal accounting control system were found to show relaxed downward stickiness of cost. This means that an enterprise with large number of workers assigned to internal accounting control system can effectively monitor the enterprise, which can efficiently control opportunistic decisions of the entrepreneur such as downward stickiness of cost. As an additional analysis, human resources were classified into departments to which persons in charge of internal accounting are affiliated to examine the effect on downward stickiness of cost. As a result of verification, high ratio of internal accounting personnel assigned to accounting department resulted in relaxed downward stickiness of cost. Accounting departments in charge of preparing for financial statements were more effectively performing monitoring work compared to other departments.

Full textAbstract:
Recent archaeological and geological surveys, combined with a neutron activation analysis, have located a new obsidian source in San Luis in the Department of Santa Bárbara of Western Honduras. From the Early Preclassic through Late Classic periods, the ancient inhabitants of the neighboring region of La Entrada acquired obsidian from San Luis and Source Y directly from outcrops and nearby streams in the form of small cobbles. These cobbles, due to their small size, were employed exclusively for the unspecialized production of percussion flakes, using a bipolar technique, for household consumption. Political boundaries played an important role in the distribution of certain imported commodities having a high exchange value: among others, Ixtepeque obsidian. It is our belief that political control over the distribution of Ixtepeque obsidian was confined more to smaller spatial configurations than to the suggested territorial political control of the segmentary states in the Maya lowlands. The distribution of goods with lower exchange values, such as the San Luis and Source Y obsidian, may have escaped political control. Small obsidian cobbles from San Luis and Source Y were apparently not distributed over long distances, but were rather essentially local resources.

Abstract Objective To examine the impact of health information exchange (HIE) on reducing laboratory tests and radiology examinations performed in an emergency department (ED). Materials and Methods The study was conducted in an ED setting in Western New York over a period of 2 months. The care of the patients in the treatment group included an HIE query for every encounter, while the care of other patients in the control group did not include such queries. A group of medical liaisons were hired to query the medical history of patients from an HIE and provide it to the ED clinicians. Negative binomial regression was used to analyze the effects of HIE queries on the number of performed laboratory tests and radiology examinations. The log files of the HIE system since 1 year before the ED admission were used to analyze the differences in outcome measures between the 2 groups of patients. Results Ceteris paribus, HIE usage is associated with, respectively, 52% and 36% reduction in the expected total number of laboratory tests and radiology examinations ordered per patient at the ED. Conclusions The results indicate that access to additional clinical data through the HIE will significantly reduce the number of laboratory tests and radiology examinations performed in the ED settings and thus support the ongoing HIE efforts.

Full textAbstract:
This thesis investigates the emergence and establishment of an early public monitoring system of the Swedish economy prior to the First World War. The study relies on a careful examination of the source materials with the view to map why and how the monitoring of the Swedish economy emerged, who demanded it, how the public supervision of the economy was organised and administrated and the results of the efforts. The common driving force was an increasing political interest in Sweden and elsewhere over the labour issue towards the end of the nineteenth century. In fact, the establishment of the monitoring system of the Swedish economy was largely the result of a broader international statistical respons to the labour question by the end of that century. The emergence of a public monitoring of the economy was driven by a general need for measuring the effect of industrialisation on the labour market, especially the growing problems with episodes of involuntary unemployment in the industrialised countries towards the end of the century. The thesis is divided in two parts with a total of ten chapters. It is written within a traditional narrative structure, that is, the beginning, the middle and the end. The first part examines the emergence of the surveillance of the labour market and consists of three chapters according to the narrative structure covering the period 1893-1913. The second part consists of three chapters that investigate the establishment of a monthly economic survey of the Swedish economy between 1910 and 1914, structured in the same way as the part one. The establishment of this early public monitoring of the Swedish economy should be regarded as a forerunner of the National Institute of Economic Research (Konjunkturinstitutet) 1937.

Alexey Vladimirovich Ivanov, a twenty-something computer geek from Chelyabinsk, Russia, in the Ural Mountains, earned his living hacking the computer networks of American companies. After breaking into a firm’s servers, he would contact it on behalf of “The Expert Group of Protection Against Hackers” and demand thousands of dollars in exchange for tips on how to plug its security holes. One Connecticut company that initially refused to pay received this e-mail from Ivanov:… now imagine please Somebody hack you network (and not notify you about this), he download Atomic software with more then 300 merchants, transfer money, and after this did ‘rm -rf/’ [a Unix command that deletes directories] and after this you company be ruined. I don’t want this, and because this i notify you about possible hack in you network, if you want you can hire me and im allways be check security in you network. What you think about this?... If a firm did not comply with his unsubtle threats, Ivanov would delete its computer files or post its customers’ credit card information on the Web. Not surprisingly, most firms gave in to the extortion. When FBI officials became aware of Ivanov’s scams, they sought help from the Russian police. But as Brendan Koerner explained, “The Russian interior ministry’s ‘Department R,’ which fights cybercrime, can barely keep up with the kontoras in St. Petersburg and Moscow, much less police a distant outpost like Chelyabinsk.” So the FBI took matters into its own hands. Under the guise of a fictional American Internet security firm called “Invita,” the FBI invited Ivanov to the United States to audition for a job identifying flaws in the networks of potential Invita clients. When Ivanov arrived, undercover agents asked him to prove his ability to break into computer networks. Unbeknownst to Ivanov, the FBI was using a “sniffer” keystroke recording program to learn the usernames and passwords for his computers in Russia. After the audition, the FBI arrested Ivanov and, using his usernames and passwords, downloaded incriminating information from his computer in Russia—information later used to convict him.

Abstract The Engineering Technology Department at Western Washington University has been using the integration of advanced Computer Aided Engineering (CAE) tools to enable a redesign of the curriculum that uses a collaborative engineering approach similar to the environment used within our industrial counterparts. In today’s competitive global marketplace, those industrial organizations must produce higher quality, easier to manufacture and maintain parts in shorter periods of time. Products are most often created in concurrent engineering or collaborative business environments where rapid sharing of information is the very essence of modern engineering. In addition, the widespread use and availability of the Internet has changed the nature of engineering data management and exchange. Therefore, CAE tools must enable engineers, analysts, technologists and designers to do their jobs more efficiently in a world where time to market is ever shortening. The best CAE tools increase productivity, because they are “smarter” tools. Only when the students are well versed in the multi-faceted collaborative engineering atmosphere and the accompanying modern CAE tools within the curriculum are they truly ready to become immediately productive in the workplace after graduation. This paper first describes the collaborative engineering approach used in the curriculum within the Engineering Technology Department during the past two years. It then describes the use of CAE tools used in the collaborative engineering approach in departmental projects. Next, it details the classes that have been specifically enabled by the use CAE tools including Engineering Design Graphics I, Engineering Design Graphics II, Numerical Control Operations, Advanced Computer Numerical Control (CNC), Tool Design, and Computer Integrated Manufacturing (which includes rapid prototyping and finite element analysis). The final section of the paper outlines future plans for enhancing the curriculum further in both the integration of computer tools and the continued development of continuing cross-disciplinary projects based on careful outcomes assessment and feedback from industrial advisory boards and professional societies.

Fuel cells (FC) technology applied to energy production could represent an effective solution to face greenhouse gas emissions and to differentiate energy sources. However, real performances of FC systems still represent a critical issue in the definition of an assessed and economically competitive technology. In fact, FC performances depend on many variables such as temperature, pressure, current, membrane humidification, stoichiometry of the reactant gas, etc.; additionally, many of these influencing parameters depend one on the other, further complicating the analysis. Numerical simulation could greatly contribute to a better understanding of the influence of design parameters. Nevertheless, the availability of experimental data to validate and to verify the numerical models is an imperative issue. The primary target of the research activity described in this paper is the set up of an experimental test bench for Proton Exchange Membrane Fuel Cell (PEM FC) at the Department of Mechanical Engineer of the University of Roma Tor Vergata aiming to completely test 8 cells 0.1 kW stack: the measured data are fundamental to validate the numerical models which have been developed by the Authors following different hierarchical levels (both semi-empirical and dimensional analytical approach) with different predictive capabilities. This apparatus allows the control of the reactant gas mass flow rates, stack pressure, humidity, current, temperature and voltage. In this way it is possible to assess a mixed experimental-numerical methodology allowing a tuning procedure for the developed models making a wide use of dedicated experimental data. The preliminary results in terms of comparisons between experimental and computational data show a good agreement even by varying some of the most performance-affecting parameters such as operating pressure and temperature.

This paper discusses the ongoing development of a ceramic regenerator for a high temperature automotive gas turbine engine sponsored by the U.S. Department of Energy. The ceramic gas turbine has a steady state gas inlet temperature of 774°C and a 982°C peak acceleration temperature which precludes the use of metallic discs. Ceramic materials have successfully operated to 982°C, with a peak acceleration temperature exceeding 1093°C. Ceramic regenerator temperature capability is currently limited by seal tribomaterial properties. The requirements of the ceramic regenerator, ceramic disc materials being evaluated, and the processing of these materials to obtain the required strength, chemical resistance, cost, including quality control are discussed. The status of the extruded regenerator program to date will also be described.

Full textAbstract:
Small modular reactors (SMRs) offer potential for addressing the nation’s long-term energy needs. However, the project design cycle for new reactor concepts is lengthy. As part of the Department of Energy’s Advanced SMR research and development program, Oak Ridge National Laboratory (ORNL) is developing a Dynamic System Modeling Tool (MoDSIM) to facilitate rapid instrumentation and controls studies of SMR concepts. Traditional nuclear reactor design makes use of verified and validated codes to meet the strict quality assurance requirements of the licensing process for the Nuclear Regulatory Commission. However, there are significant engineering analyses and high-level decisions required prior to the rigorous design phase. These analyses typically do not require high-fidelity codes. Different organizations and researchers may examine various plant configuration options prior to formal design activities. Engineers and managers must continuously make down-selection decisions regarding potential reactor architectures and subsystems. Traditionally, the modeling of these complex systems has been based on legacy models. Considerable time and effort are necessary to understand and manipulate these legacy models. For trade-space studies, two developments in the model-based systems engineering space represent a significant advancement in the ability of engineering tools to meet these demands. The first is Modelica: a nonproprietary, equation-based, object-oriented modeling language for cyber-physical systems. The second is the Functional Mockup Interface: a standardized, open interface for model exchange, simulation, and deployment. ORNL’s MoDSIM tool makes use of these developments and is intended to provide a flexible and robust dynamic system-modeling environment for SMRs. This includes single or multiple reactors, perhaps sharing common resources, or producing both electricity and process heat for local consumption or feeding a regional grid. MoDSIM uses the open-source modeling language (Modelica) and incorporates a user interface, coupled dynamic models, and analysis capabilities that will enable non-expert modelers to perform sophisticated end-to-end system simulations of both neutronic and thermal-hydraulic models. This approach enables open-source and crowd-source-type collaborations for model development of SMRs in an approach similar to open-source and open-design techniques currently used for software production and complex system design. As part of the tool development, an example SMR was chosen (advanced liquid metal reactor [ALMR]) and the ALMR models developed and interface tools demonstrated. For initial verification purposes, the results from these Modelica simulations are compared with the results documented for the earlier ALMR power-reactor innovative small-module concept. These results, as well as initial demonstrations of the tool for different control strategies, are presented in this paper.

The Hanford Site in southeastern Washington State has been used extensively by the U.S. Department of Energy (DOE) to produce nuclear materials for the U.S. strategic defense arsenal. A large inventory of radioactive and mixed waste has accumulated in 177 buried single- and double-shell tanks. Liquid waste recovered from the tanks will be pre-treated to separate the low activity fraction from the high-level and transuranic wastes. The low-activity waste (LAW) will be immobilized in glass and placed in a near-surface disposal system on the Hanford Site. Vitrifying the LAW will generate over 160,000 m3 of glass. Before the immobilized low-activity waste (ILAW) can be disposed, DOE must approve a performance assessment (PA), which is a document that describes the long-term impacts of the disposal facility on public health and environmental resources. A sound scientific basis for determining the long-term release rates of radionuclides from LAW glasses must be developed if the PA is to be accepted by regulators and stakeholders. To conduct this calculation, Pacific Northwest National Laboratory (PNNL) used a methodology in which the waste form release rate was calculated by modeling the basic physical and chemical processes that are known to control dissolution behavior using a reactive transport code, STORM [1]. This methodology was used instead of empirical extrapolations from laboratory “leaching” experiments commonly used in other PA or in the phenomenological approach of SIA “Radon” [2]. This methodology is preferred because the dissolution rate, and hence radionuclide release rate, from silicate glasses is not a static variable—a constant that can be derived independently of other variables in the system. Glass dissolution rate is a function of three variables (neglecting glass composition itself): temperature, pH, and composition of the fluid contacting the glass. SIA Radon has been running a field experiment for over 12 years to evaluate the behavior of a high sodium glass buried in a loamy soil. The radioactive waste glass (K-26) made from actual intermediate-level waste from the Kursk (RBMK) reactor was manufactured and placed in a shallow trench. The waste stream was 86 mass% NaNO3, very similar to the salt content expected for Hanford LAW. The final glass composition had a Na2O content of roughly 16 mass%, making it very relevant to the glass formulations being considered at Hanford. A joint US DOE-SIA Radon project was devised to validate the modeling approach used for the ILAW PA by modeling glass corrosion in the subsurface experimental facility [3]. This paper gives an estimate of glass corrosion and ion exchange rates for K-26 waste glass based on field measurements.

Abstract The DDG 51 Class of AEGIS guided missile destroyers is the Navy’s premier surface combatant. Named for famed World War II hero. Admiral Arleigh Burke, these ships represent state-of-the-art technology. This 504 foot, 8,300 ton destroyer has been designed with improved seakeeping and survivability characteristics and carries the sophisticated AEGIS Weapon System. Derived from the Greek word meaning “shield”, AEGIS ships are the “shield of the fleet”. The Navy has commissioned the first two ships of the class. They have performed beyond expectation in rigorous at-sea trials designed to fully test combat capability. The DDG 51 Class ships are replacing retiring fleet assets. In a decreasing Department of Defense (DoD) budget environment, however, acquisition costs must be reduced to continue to build capable warships. The Navy’s Destroyer Program Office is pursuing the implementation of Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) technology to reduce costs without reducing ship’s capability. Under Navy direction, the ship construction yards, Bath Iron Works and Ingalls Shipbuilding, are aggressively pursuing the transition to CAD-based design, construction, and life cycle support This effort also involves General Electric, the Combat System Engineering Agent. Building a three dimensional (3D) computer model of the ship prior to construction will facilitate the identification and resolution of interferences and interface problems that would otherwise go undetected until actual ship construction. This 3D database contains geometry and design data to support system design. Accurate construction drawings, fabrication sketches, and Numerical Control (NC) data can be extracted directly from the database to support construction at each shipyard. At completion of construction, a model representing the “as built” configuration will be provided as a lifetime support tool for each ship’s projected 40 year life. The transition to CAD-based design and construction has applied fundamental concepts of the DoD’s Computer Aided Acquisition and Logistic Support (CALS) initiative. In addition to creating a 3D database representing ship design, the shipyards have developed a neutral file translator to exchange this data between Computervision and Calma CAD systems in operation at Bath Iron Works and Ingalls Shipbuilding respectively. This object oriented transfer capability ensures data is shared rather than duplicated. The CALS concepts of concurrent engineering and computer aided engineering analysis are being applied to design an upgrade to the ship that features the addition of a helicopter hanger. The CAD models are used as an electronic baseline from which to assess proposed modifications. Optimizing the design before the first piece of steel is cut will reduce construction costs and improve the quality of the ship.

Full textAbstract:
The aim of this study was to provide a characterization of non-symmetrical operation in two counter-flow primary surface exhaust gas recuperators installed in parallel flow loops. The hybrid system emulator test rig and facility designed and operated by the Department of Energy, National Energy Technology Laboratory located at the West Virginia (USA) campus was used for the study. Various tests from the past years often resulted in non-symmetrical operation, indicated by significantly variant temperature measurements at the outlets of the recuperators. Some specific tests have been carried out in order to identify the possible cause of this flow unbalance. The isolated effects of bleed air, cold air and hot air valve on the heat exchangers flow unbalance have been studied. Also, the impact of load bank changes on flow distribution has been considered in this study. Each test has been carried out in close loop fuel valve speed control. The influence of each independent variable in the study on parallel recuperator flow distribution has been quantitatively characterized using temperatures and a heat balance. Both the bleed and the cold air compressor bypass valves showed an appreciable impact on the heat exchangers flow unbalance, while hot air valve and load bank changes had minimal effect.

Full textAbstract:
Abstract Four different control methods for ramping down the power output from a Supercritical Carbon Dioxide (sCO2) simple cycle were studied to support the development of 10 MWe Pilot Plant Test Facility, funded by the US Department of Energy. These detailed transient models are written using NPSS (Numerical Propulsion System Simulation). The main components of the NPSS models include a compressor, turbine, High-Temperature Recuperative heat exchanger (HTR), cooler, heater, pipes, and valves. In the transient models, the thermal mass and CO2 fluid volume for each main component are based on representative data or proven design practices for the corresponding component. The steady-state performance of each main component has been validated with representative data while the transient performance of the HTR has been validated with published experimental data. The models have been used to study the methods to ramp down the power output. The methods include extracting the CO2 from the inventory, reducing the opening of turbine inlet throttle valve, and increasing the temperature of the cooling water entering the cooler. These methods, along with a hybrid method of combining the first two methods, were evaluated for the rate of turndown in the power output, operability of the compressor, and cycle efficiency. The preliminary results suggest that inventory extraction is the most efficient but has a slow turndown rate while turbine throttle control is less efficient but results in a faster turndown rate. In addition, the inventory extraction reduces the margin of the compressor choke line but the turbine throttle control increases the margin of the choke line.
