Abstract:

Objective: Experimental estimate of the secondary radiation on the surface of implants and expanders, used for breast reconstruction in case of mastectomy, after making radiation therapy.Methods: Special equipment was constructed by radiation study department. It consists of linear accelerator as a source of ionizing radiation and a gamma-ray spectrometer with the detector on the basis of ultrapure germanium. The objects of research were the implants and expanders of the different producers.Results: The maximum amount of the secondary photons on the implants and expanders was generated on the energy level lower than 700 KEV. The level of photons’ generation between 600–300 KEV was higher on the surface of the implants than on the surface of expander filled with saline.Conclusion: The photons of the secondary radiation with the energy level from 100 to 700 KEV are generated under the influence of ionizing radiation on the implants and tissue expander filled with saline. It can be one of the causes of capsular contractures development after mastectomy.

Abstract:

Expander which drives an electromotor to generate electricity is the core of low-temperature waste heat recovery equipment. At present, domestic expanders on waste heat recovery system mostly arise from exploration, research and improvement on the existing models of screw expanders and scroll expanders, which have complex structures and high costs. For overcoming the shortcomings mentioned above, a new roots-type power machine is researched and designed. In this paper, the working fluid of low pressure waste heat is stimulated according to both the different operating conditions and the different intake and exhaust pressure and flow, and the changing process of internal flow field is simulated over the time period using dynamic mesh technique when the power machine is in rotating work. Besides, the pressure field, velocity field and graph of mass flow rate are analyzed with the simulation results, thus obtaining the conclusion of optimum operating conditions of the roots-type power machine to guide selection method in practice, that is, selecting appropriate roots-type power machines according to different types of waste heat in industrial production. These efforts can therefore provide strong theoretical guidance and foundation for the subsequent engineering practice of waste heat recovery system on roots-type power machine, and can have a profound impact on further recovery and utilization of low-grade energy.

Abstract:

A novel compressed air energy storage (CAES) system has been developed, which is innovatively integrated with a coal-fired power plant based on its feedwater heating system. In the hybrid design, the compression heat of the CAES system is transferred to the feedwater of the coal power plant, and the compressed air before the expanders is heated by the feedwater taken from the coal power plant. Furthermore, the exhaust air of the expanders is employed to warm partial feedwater of the coal power plant. Via the suggested integration, the thermal energy storage equipment for a regular CAES system can be eliminated and the performance of the CAES system can be improved. Based on a 350 MW supercritical coal power plant, the proposed concept was thermodynamically evaluated, and the results indicate that the round-trip efficiency and exergy efficiency of the new CAES system can reach 64.08% and 70.01%, respectively. Besides, a sensitivity analysis was conducted to examine the effects of ambient temperature, air storage pressure, expander inlet temperature, and coal power load on the performance of the CAES system. The above work proves that the novel design is efficient under various conditions, providing important insights into the development of CAES technology.

Abstract:

This paper provides an overview of a one-dimensional modelling methodology for equipment and systems for heat to power conversion based on a staggered grid space discretization and implemented in the commercial software GT-SUITE®. Particular attention is given to a newly developed modelling procedure for twin-screw machines that is based on a chamber modelling approach and considers leakage paths between cells and with the casing. This methodology is then applied to a low-grade heat to power conversion system based on a Trilateral Flash Cycle (TFC) equipped with two parallel two-phase twin-screw expanders and a control valve upstream of the machines to adapt the fluid quality for an optimal expander operation. The standalone expander model is used to generate performance maps of the machine, which serve as inputs for the TFC system model. Parametric analyses are eventually carried out to assess the impact of several operating parameters of the TFC unit on the recovered power and cycle thermal efficiency. The study shows that the most influencing factors on the TFC system’s performance are the inlet temperature of the heat source and the expander speed. While the first depends on the topping industrial process, the expander speed can be used to optimize and control the TFC system operation also in transient or off-design operating conditions.

Abstract:

The thermal efficiency of a Carnot cycle is limited by the maximum and minimum temperatures available. The construction of LNG (liquid natural gas) terminals and the need to vaporize LNG offers a cooling source at a very much lower temperature than sea water. By using the cold sink and by adapting the waste heat available from a combined cycle plant, it is possible to recover power from the vaporization of LNG. This is done by the use of a reverse cascade refrigeration process where energy is extracted by expanders instead of energy input by compressors. The paper explains how the hot and cold processes can be integrated to produce a compound cycle with an overall efficiency of some 55 per cent or more depending on the quantity of LNG to be vaporized. Special reference is given to the features needed for the rotating equipment and how equipment selection is critical to the realization of a practical working power station.

Abstract:

Foothills Pipe Lines Ltd. is the Canadian sponsor of the Alaska Natural Gas Transportation System (ANGTS), a pipeline project selected in Canada and the United States as the means for transporting Alaskan gas reserves to the lower 48 United States. Currently, certain Prebuild portions of the ANGTS are in operation delivering Canadian gas to U. S. markets. A recent system expansion of the Eastern Leg Prebuild to accommodate increased Canadian gas exports entailed the construction of Decompression/Recompression facilities at Empress, Alberta to enable high-pressure operation of the Foothills pipeline while maintaining gas stripping at existing lowpressure extraction plants. The general process of the Decompression/Recompression facilities involves the expansion of high-pressure pipeline gas to conditions acceptable to the low-pressure extraction plants, then the recompression of the residue gas for return to the pipeline at original pressure. By directing the inlet gas through turbo expanders coupled to brake compressors, a substantial portion of the expansion energy is captured and used in providing the first stage of gas recompression. Including supplemental conventional compression, the Decompression/Recompression facilities are capable of providing approximately 37MW (50,000 HP) for continuous gas recompression. Although power recovery with turbo expanders is relatively common in the gas processing industry, such an application for gas recompression in large gas pipelines is unique. This technical paper describes the Foothills Decompression/Recompression facilities with their utilization of turbo expanders for pipeline recompression service, emphasizing the process design as well as the characteristics of the rotating equipment.

Abstract:

Ejectors used in refrigeration systems as entrainment and compression components or expanders, alone or in combination with other equipment devices, have gained renewed interest from the scientific community as a means of low temperature heat recovery and more efficient energy use. This paper summarizes the main findings and trends, in the area of heat-driven ejectors and ejector-based machines, using low boiling point working fluids, which were reported in the literature for a number of promising applications. An overall view of such systems is provided by discussing the ejector physics principles, as well as a review of the main developments in ejectors over the last few years. Recent achievements on thermally activated ejectors for single-phase compressible fluids are the main focus in this part of the review. Aspects related to their design, operation, theoretical and experimental approaches employed, analysis of the complex interacting phenomena taking place within the device, and performance are highlighted. Conventional and improved ejector refrigeration cycles are discussed. Some cycles of interest employing ejectors alone or boosted combinations are presented and their potential applications are indicated.

Abstract:

This paper presents an innovative concept of using air-cycle technology for the development of a microclimate cooling device for use by soldiers in the battlefield. The device is an integrated heat engine and heat pump which supplies air at a prescribed temperature and humidity for personal cooling of a soldier wearing protective ensembles, generates electrical energy to power communication equipment, and produces drinking water by condensing atmospheric moisture which may be very useful in desert warfare. It consists of a centrifugal compressor, two turbines or expanders, a combustion chamber, three heat exchangers, a water separator, and an electric generator. Atmospheric air is used as the working fluid in both the engine and cooling loops and diesel is used as the fuel for combustion. A detailed thermodynamic analysis and design optimization was performed. It was found that the system efficiency increases with operating pressure ratio, attains a maximum, and decreases with further increase of pressure ratio. The system efficiency was found to be also dependent on the air-fuel ratio, and the maximum efficiency was found to occur at a specific air-fuel ratio, for any given pressure ratio. The optimum operating condition determined from the thermodynamic analysis was used to outline a detailed design of the system.

Abstract:

O presente trabalho tem como objetivo estudar a técnica da Expansão Rápida da Maxila, comparando os tipos de aparelhos recomendados consoante as diferentes propriedades, vantagens e desvantagens associadas. Quando pensamos em um padrão normal para a oclusão temos em mente uma correta relação entre as bases apicais em que a arcada maxilar deverá englobar a arcada mandibular permitindo o equilíbrio entre ambas. Quando ocorre uma redução das dimensões transversais da maxila nos vemos diante de atresias, entre elas uma anomalia de má oclusão bastante frequente na nossa clínica, a mordida cruzada posterior. Quando isto acontece o profissional precisa buscar uma correção da conformação do arco através da expansão rápida da maxila abrindo a sutura palatina mediana por meio de aparelhos expansores fixos tais como o de Haas (dento-muco-suportado) ou os classificados como dento-suportados como o Hyrax ou o disjuntor de McNamara, na dentição decídua, mista ou permanente e até mesmo em pacientes adultos com protocolos diferenciados para cada faixa etária. Caso o indivíduo apresente uma calcificação óssea avançada da sutura mediana deve ser encaminhado para a expansão rápida da maxila cirurgicamente assistida.
The present work aims at studying the technique of the Rapid Maxillary Expansion, comparing the types of recommended devices, according to their different properties, associated advantages and disadvantages. When we think of a normal pattern for the occlusion we have in mind a correct relationship between the apical bases in which the maxilar arcade, thus allowing the balance between maxilla and mandibule. When there is a reduction of transverse dimensions of the patient`s jaw, we are confronted with so-called artresia, including a malocclusion is common in our clinic, the posterior crossbite. When this happens the professional must seek a correction of the conformation of the arc by rapid maxillary expansion by opening the palatal suture by fixed appliances such as expanders Haas (dental-mucus-supported) or those classified as dental-supported between like Hyrax or McNamara breaker, in deciduous, mixed or permanent dentition, and even in adult patients with different protocols for each age group. If the patient already presents an advanced bone calcification of the median suture, he must be sent to the surgically assisted maxillary expansion.

It proposes that, as literary forms, the proverbs share the massively distributed, viscous and non-local qualities of Timothy Morton’s hyperobjects. In Ronsard’s 1572 epic the significance of the aftermath of the Trojan war turns out to have extended far beyond Virgil’s Aeneid and the foundation of Rome, to the foundation of Paris and a yet-to-be-realized early modern French empire. La Franciade’s proverbs challenge their readers to perceive and respond to these vastly expanded relations, even as they progress through apparently local narrative time., On this basis, they might also equip their readers to engage with the dissonant scales of ongoing global ecological crisis.

Abstract:

The “Maytag repairman” is the familiar image of field service. When servicing electronic equipment such as computers, however, the job is significantly more demanding than fixing washing machines. Not only are computers more complex than most other machines, they are also more central to the ongoing operations of an organization. Increasingly, everything an organization does depends upon electronic equipment in some way. Large computer systems are often expected to run 24 hours a day, 365 days a year. When computers are such an integral part of an organization’s operations, maintaining the equipment is tantamount to keeping a person’s heart beating and blood circulating. Thus, unlike the idle television caricature, field service engineers are increasingly viewed as the paramedics for electronics who can quickly and ably respond to system crashes. At the same time that field service has become more demanding, the complexity of the job has increased. The “machinery” of the modern organization is less often composed of gears turning, typewriters clattering, and paper being shuffled. Instead, the sights and sounds of the modern organization consist of screens glowing, keys clicking, and, to the uninitiated, an assemblage of opaque, “black boxes.” Inside these boxes is a miniature world that gives no clue as to the nature of its inner workings. The field service engineer’s (FE) job and function have been growing while the size of the technology itself has been shrinking. His or her skill is less often exercised as a skilled craftworker in the repair of a part and more often as a skilled analyst who can understand the abstract workings and nature of electronics to identify the problem and trace it to the malfunctioning component. The required manual skills are often minimal, just enough dexterity to swap out a bad part for a good one usually suffices. At the same time, the scope of field service has expanded from just repairing worn and broken or defective parts to collecting information about design defects and debugging equipment that may have been released prematurely.

Full text

Abstract:

The discipline of industrial engineering (IE) was originated in the US by Frederick W. Taylor, who first applied what he termed scientific management to machine shop management in the 1880s. IE expanded world-wide with applications of work measurement to all manner of manufacturing, then to services. A century later, as the Japanese practice of Total Productive Maintenance (TPM) became known in the US, the associated equipment management metric Overall Equipment Effectiveness (OEE) became well-known as a production metric that could be applied to individual manufacturing machines, production lines, and the overall production system. In this chapter, illustrations of the calculation of OEE are provided, along with modification of the three OEE inputs (availability, performance efficiency, and quality rate) to create a new service management metric Overall Service Effectiveness (OSE). Definitions and measures of service quality are reviewed. The first published application of OSE was to a city public transportation system, and is reviewed as a prototype. Essentially, applications of OSE require the industrial engineer to define service-specific measures of availability, processing rate, and quality at the management’s level of interest: work station, process, or system. The data collected to calculate OSE will also point toward actions that would improve OSE.

Abstract:

This chapter will provide background to enable the reader to understand basic statistics and be able then to follow more complex statistical ideas. Although statistics is more than the mere analysis of data, it is a subject largely about data, so this will be discussed first. Data can be categorical or numerical, and in these two classifications there are various different types of data. This is the allocation of the individual to one of two categories. Often these relate to the presence or absence of some attribute. These data also have many other names such as binary, dichotomous and attribute data. Examples of such categorisations for patients include: ◆ Male/Female ◆ Smoker/Non-smoker ◆ Anaesthetist/Surgeon ◆ Married/Single. Each of these can be only be one or the other – they could be coded ‘1’ or ‘0’ to be binary (or on, off). For example male = 0, female = 1, or vice versa. Many classifications require more than two categories, such as: blood group, type of doctor, country of birth. Also the two categories, such as described previously, might be expanded into several categories. For example the married/single could be expanded to: married/single/divorced/separated/ widowed. This sort of data is called nominal data where there are several categories, but with no logical order. When there is a natural order (such as in seniority), the data are then called ordinal data. For example, anaesthetists could be divided into: ‘Foundation year 1’, ‘Foundation year 2’, ‘speciality doctor’, consultants’, ‘senior consultants’ and ‘clinical directors’. Ordinal data can be reduced to two categories, with possibly a considerable loss of information (e.g. ‘senior doctors’, ‘junior doctors’). Discrete numerical data are where the observation takes exact numerical values. Counts or events are discrete values. For example: number of children, number of ectopic beats in a time period and so on. Continuous (or analogue) data are usually obtained by some form of measurement. Examples are body temperature, blood pressure, height and weight. These values have an infinite number of possibilities, depending on the measurement interval, and variation. Although there are infinite possibilities, measurement systems usually round the continuous data up, or down, to discrete values. Blood pressure is often rounded up to the nearest 5 mmHg, for example.

Abstract:

Enterprise resource planning (ERP) is a state-of-the-art approach to running organizations with the help of comprehensive information systems, providing support for key business processes and more general, for electronic business (e-business). ERP has evolved from earlier approaches, in particular, materials requirement planning (MRP) and manufacturing resource planning (called MRP II) in the 1980s. The focus of MRP and MRP II was on manufacturing firms. The essential problem that MRP attacked was to determine suitable quantities of all parts and materials needed to produce a given master production schedule (also called a “production program”), plus the dates and times when those quantities had to be available. Application packages for MRP have been available from the 1960s on. In the beginning, they were mostly provided by hardware vendors like IBM, Honeywell Bull, Digital Equipment, Siemens, etc. MRP was later expanded to closed-loop MRP to include capacity planning, shop floor control, and purchasing, because as Oliver Wight (1884) puts it: “Knowing what material was needed was fine, but if the capacity wasn’t available, the proper material couldn’t be produced” (p. 48). The next step in the evolution was MRP II (manufacturing resource planning). According to the father of MRP II, Oliver Wight, top management involvement in the planning is indispensable. Therefore, MRP II expands closed-loop MRP “to include the financial numbers that management needs to run the business and a simulation capability” (Wight, 1984, p. 54). Enterprise resource planning (ERP) has its roots in the earlier MRP II concepts, but it extends those concepts substantially into two directions. ERP takes into account that other types of enterprises than those producing physical goods need comprehensive information system (IS) support as well, and even in the manufacturing industry, there are more areas than those directly related to the production of goods that are critical for the success of a business.

After more than twenty years working on the selection of an appropriate expander for Organic Rankine cycles and wide research and attentions about its influence on the performance and total cost of waste heat recovery systems, now there is a good-enough background studies and achievement for large scale applications. But small-scale industries is like a art space to modify and revise the previous results. As it is clearly known, in small-scale applications and industries especially in internal combustion engines, besides the investigation of performance, physical properties and final efficiency of expander, other parameters should be analyzed accurately like manufacturing cost, availability, reliability, sensitivity to operating condition fluctuations. Due to a significant role of expander equipment to enhance the efficiency of ORC system in the first step expanders is investigated. In this paper, as per related operating characteristics, a complete comparison of small-scale expanders will be debated to guide designers to select more appropriate and the best efficient expansion machine as per their requirements. According to available literatures there is more need to do research about different types of expanders with various operating conditions in small-scale industries.

Abstract:

Abstract The different economics of small scale LNG plants put more emphasis on capital expenses over process efficiency, and thus favors simpler refrigeration cycles. We typically find reverse Brayton cycles, or SMR (Single mixed refrigerant) cycles. These cycles have specific requirements to the compression equipment, and typically have smaller drivers, either electric drives or gas turbines. The relationship between output, driver size, and process preferences is explained. The type of compressors, and expanders needed are discussed, together with thoughts and the driver preferences. This includes the different control methods that can be used, both for the cycle adaptation, as well as the related control of the compressors, expanders, valves and drivers. Equipment performance maps are created to highlight the required different operating conditions. This result allows for subsequent optimization discussions.

Abstract:

With the development of offshore oil and gas industry, LNG turbo expanders are widely used in Floating Liquid Natural Gas equipment (FLNG) for natural gas transportation. The performance characteristic of the turbo expander is significant affected by the rolling motion caused by the ocean conditions. As an important part of expander, the labyrinth seal is directly related to the safety of the expander, so it is necessary to study the performance characteristic of labyrinth seal under rolling motion. In this paper, CFD is used to simulate the internal flow field of labyrinth seals under different rolling periods and sloshing amplitudes conditions. The distribution of the pressure drop is obtained, and the influence of rolling motion on different labyrinth seal radial clearances and cavity depths are discussed. The results indicate that variation periods of the pressure drop are consistent with the rolling periods, and the larger the rolling amplitude is, the larger pressure drop fluctuation can be observed. Additionally, the fluctuation characteristic is significantly affected by gap widths and cavity depths.

Abstract:

This paper provides an overview of the use of pullout testing to determine the optimum parameters for assuring reliable tube to tubesheet joints in condensers and heat exchangers. The test is described with typical test methods, equipment and test precautions. Numerous examples of data from a variety of units, tube materials, and tubesheet materials are presented. Also included are unique tests which were performed to qualify the tube expansion procedures prior to use in nuclear facilities. These tests include mockups for pneumatic and helium leak testing, and hydrostatic testing of mockups with rolled test joints at over 600 psi. Examples will include testing with 3 roll expanders compared to 5-roll expanders in heavy gauge titanium tubes, test results with a double tubesheet arrangement, and high strength joints with thin wall titanium tubes in brass tubesheets. An example comparing the pullout forces determined with a HEI beam strip analysis to the actual pullout test data is also discussed.

Abstract:

Foothills Pipe Lines Ltd. is the Canadian sponsor of the Alaska Natural Gas Transportation System (ANGTS), a pipeline project selected in Canada and the United States as the means for transporting Alaskan gas reserves to the lower 48 United States. Currently, certain Prebuild portions of the ANCTS are in operation delivering Canadian gas to U.S. markets. Recent system expansion of the Eastern Leg Prebuild to accommodate increased Canadian gas exports entailed the construction of Decompression/Recompression facilities at Empress, Alberta to enable high pressure operation of the Foothills pipeline while maintaining gas stripping at existing low pressure extraction plants. The general process of the Decompression/Recompression facilities involves the expansion of high pressure pipeline gas to conditions acceptable to the low pressure extraction plants, then the recompression of the residue gas for return to the pipeline at original pressure. By directing the inlet gas through turbo expanders coupled to brake compressors, a substantial portion of the expansion energy is captured and used in providing the first stage of gas recompression. Including supplemental conventional compression, the Decompression/Recompression facilities are capable of providing approximately 37 MW (50 000 HP) for continuous gas recompression. Although power recovery with turbo expanders is relatively common in the gas processing industry, such application for gas recompression in large gas pipelines is unique. This technical paper describes the Foothills Decompression/Recompression facilities with their utilization of turbo expanders for pipeline recompression service, emphasizing the process design as well as the characteristics of the rotating equipment.

Abstract:

Overhung-configuration rotors are commonly used in the oil, gas and process industries. Examples of this type of equipment include power turbines, Fluid Catalytic Cracking (FCC) expanders, turbochargers and pipeline boosters. Generally, in overhung-configuration rotors, the mass concentration is near the bearing on the overhung end, so the rotor dynamics behavior of these overhung-configuration rotors is different than other equipments that have their mass concentrations between the bearing spans, such as multistage compressors. Among the more important characteristics that directly affect the rotor dynamics of the overhung rotors are gyroscopic effects on the higher modes and the fluid-film journal bearings. Gyroscopic effects are more significant in overhung configurations because of the relatively large overhung mass. These rotors also have a short bearing span and a relatively stiff shaft, so the first two modes are characterized by rigid body motion, as long as the bearing supports are rigid, as in most pipeline boosters. For pipeline boosters it would be typical to describe them as subcritical machines. If the bearing supports are not rigid, as at the disc end of power turbines and FCC expanders, then the first mode can be amplified, and it would not be unusual to describe them as supercritical machines. This paper will assume that the bearing supports are rigid, as in most pipeline boosters. A phenomenon observed in overhung rotors is known as the synchronous thermal instability or “Morton Effect”. The Morton Effect occurs when synchronous vibration produces non-uniform heating of the shaft under the bearing, leading the shaft end to develop a thermal bow. It is typical for this to happen on the overhung end of the rotor, where there is more unbalance to react with any thermal bow. The paper examines the hysteretic dynamic behavior observed in an overhung rotor mounted on tilting pad journal bearings, presenting a series of analysis using state-of-the-art rotor dynamics programs, and comparing analytical results with measurements, handling possible variables associated with synchronous “hysteresis” vibration.
