OBJETIVO: verificar os tempos máximos de fonação (TMF) de vogais e correlacionar os resultados das relações entre /e/ áfono e sonoro (ė/e), s/z e TMF obtido/previsto (TMFO/TMFP), conforme o sexo, em futuros profissionais da voz adultos com voz normal. MÉTODO: seleção por meio de avaliação vocal pela escala RASATI; coleta dos TMF /a, i, u, e, s, z/, do /e/ áfono (/ė/) e da capacidade vital; cálculo das relações s/z, ė/e e TMFO/TMFP de 50 mulheres (média 21,42 anos) e 12 homens (média 24,25 anos). RESULTADOS: em ambos os sexos, os TMF estiveram significantemente dentro da normalidade ou com valores diminuídos, sugerindo equilíbrio ou escape aéreo à fonação. Relação s/z significantemente normal, relação ė/e significantemente aumentada quando comparada aos resultados diminuídos e, relação TMFO/TMFP sem diferenças significantes. Resultados que apontaram equilíbrio ou hipercontração de pregas vocais à fonação. Correlação positiva significante apenas entre as relações ė/e e s/z mostrando que crescem proporcionalmente e que a relação TMFO/TMFP não se correlaciona com elas. CONCLUSÃO: os futuros profissionais da voz adultos e com voz normal estudados em sua maioria apresentaram os TMF de vogais dentro da normalidade ou diminuídos, a relação s/z normal; a relação ė/e com valores aumentados quando comparada ao grupo com valores diminuídos, sugerindo a presença de incoordenação pneumofonoarticulatória. A correlação positiva entre as relações ė/e e s/z sugere que ambas fornecem resultados compatíveis entre si, não ocorrendo o mesmo com a relação TMFO/TMFP.

Abstract:

Motional averaging has been proven to be significant in predicting the chemical shifts inab initiosolid-state NMR calculations, and the applicability of motional averaging with molecular dynamics has been shown to depend on the accuracy of the molecular mechanical force field. The performance of a fully automatically generated tailor-made force field (TMFF) for the dynamic aspects of NMR crystallography is evaluated and compared with existing benchmarks, including static dispersion-corrected density functional theory calculations and the COMPASS force field. The crystal structure of free base cocaine is used as an example. The results reveal that, even though the TMFF outperforms the COMPASS force field for representing the energies and conformations of predicted structures, it does not give significant improvement in the accuracy of NMR calculations. Further studies should direct more attention to anisotropic chemical shifts and development of the method of solid-state NMR calculations.

Abstract:

The five Crystal-Structure Prediction (CSP) Blind Tests have shown that molecular-mechanics force fields are not accurate enough for crystal structure prediction[1]. The first--and only--method to successfully predict all four target crystal structures of one of the CSP Blind Tests was dispersion-corrected Density Functional Theory (DFT-D), and this is what we use for our work. However, quantum-mechanical methods (such as DFT-D), are too slow to allow simulations that include the effects of time and temperature, certainly for the size of molecules that are common in pharmaceutical industry. Including the effects of time and temperature therefore still requires molecular dynamics (MD) with less accurate force fields. In order to combine the accuracy of the successful DFT-D method with the speed of a force field to enable molecular dynamics, our group uses Tailor-Made Force Fields (TMFFs) as described by Neumann[2]. In Neumann's TMFF approach, the force field for each chemical compound of interest is parameterised from scratch against reference data from DFT-D calculations; in other words, the TMFF is fitted to mimic the DFT-D energy potential. Parameterising a dedicated force field for each individual compound requires an investment of several weeks, but has the advantage that the resulting force field is more accurate than a transferable force field. Combining crystal-structure prediction with DFT-D followed by molecular dynamics with a tailor-made force field allows us to calculate e.g. the temperature-dependent unit-cell expansion of each predicted polymorph, as well as possible temperature-dependent disorder. This is relevant for example when comparing the calculated X-ray powder diffraction patterns of the predicted crystal structures against experimental data.

Abstract:

Este estudo objetivou verificar a influência do dreno torácico intercostal fechado com selo d’água na respiração e voz, em sujeitos portadores de doenças pleuropulmonares. Foram avaliados 18 sujeitos com drenagem torácica intercostal fechada com selo d’água de ambos os sexos, com faixa etária de 18 a 74 anos de idade. Foram realizadas duas avaliações envolvendo voz e respiração, sendo a primeira, 48 horas após a colocação do dreno e, a segunda, logo após a retirada do dreno, incluindo anamnese respiratória e fonoaudiológica; medidas de cirtometria do tórax; propedêutica pulmonar; testes de medidas de Pimax e Pemax; testes de função pulmonar, avaliando o VCI e CVF; testes pneumofonoarticulatórios (TMF, CFS, CFC, TMFP e TMFO) e questionário sobre o comportamento da respiração e voz. O comportamento dos dois grupos se assemelhou, em termos de medida-resumo, com médias da cirtometria com dreno SAIF 91,58 cm, SAEF 89,69 cm, XIF 93,17 cm, XEF 91,11cm, BIF 88,17cm e o BEF 86,08 cm. As médias da pressão respiratória máxima foram: Pimax 71,11 cm H2O, Pemax 61,94 cm H2O. Quanto às médias da função pulmonar: VCI 427,78ml, CVFNNO 2169,44 ml e CVFNO 2316,11ml. Sem dreno: SAIF 92,08 cm, SAEF 89,08 cm, XIF 92,86 cm, XEF 90,36 cm, BIF 88,67 cm e BEF 85,36 cm e as médias da pressão respiratória máxima foram: Pimax 82,72 cm H2O, Pemax 73,56cm H2O. Quanto às médias da função pulmonar: VCIArtigo original440,17 ml, CVFNNO 2587,22 ml e CVFNO 2762,22 ml. Na avaliação da voz com dreno, a média da CFS foi de 209,58, CFC de 207,05, TMFP 12,15s, TMFO/TMFP de 1,03s e, sem o dreno, a média da CFS foi de 134,15, CFC de 95,42, TMFP 2,81s, TMFO/TMFP de 0,54s. Concluiu-se que o dreno não exerce influência quanto às medidas da mecânica respiratória; apesar dos sujeitos permanecerem com as mesmas alterações pulmonares, não houve diferença quanto ao tempo pneumofonoarticulatório; o nível de sensação de desempenho respiratório e vocal aumentou com o uso do dreno.

Abstract:

ObjectiveHealth technology reassessment (HTR) is a field focused on managing a technology throughout its life cycle for optimal use. The process results in one of four possible recommendations: increase use, decrease use, no change or complete withdrawal of the technology. However, implementation of these recommendations has been challenging. This paper explores knowledge translation (KT) theories, models and frameworks (TMFs) and their suitability for implementation of HTR recommendations.DesignCross-sectional survey.ParticipantsPurposeful sampling of international KT and HTR experts was administered between January and March 2019.MethodsSixteen full-spectrum KT TMFs were rated by the experts as ‘yes’, ‘partially yes’ or ‘no’ on six criteria: familiarity, logical consistency/plausibility, degree of specificity, accessibility, ease of use and HTR suitability. Consensus was determined as a rating of ≥70% responding ‘yes’. Descriptive statistics and manifest content analysis were conducted on open-ended comments.ResultsEleven HTR and 11 KT experts from Canada, USA, UK, Australia, Germany, Spain, Italy and Sweden participated. Of the 16 KT TMFs, none received ≥70% rating. When ratings of ‘yes’ and ‘partially yes’ were combined, the Consolidated Framework for Implementation Research was considered the most suitable KT TMF by both KT and HTR experts (86%). One additional KT TMF was selected by KT experts: Knowledge to Action framework. HTR experts selected two additional KT TMFs: Co-KT framework and Plan-Do-Study-Act cycle. Experts identified three key characteristics of a KT TMF that may be important to consider: practicality, guidance on implementation and KT TMF adaptability.ConclusionsDespite not reaching an overall ≥70% rating on any of the KT TMFs, experts identified four KT TMFs suitable for HTR. Users may apply these KT TMFs in the implementation of HTR recommendations. In addition, KT TMF characteristics relevant to the field of HTR need to be explored further.

Abstract:

Abstract:Disturbance is a central process in forest dynamics, yet the role of natural disturbance in tropical montane forests (TMFs) has not been systematically addressed. We posit that disturbance in TMFs has a wider role than commonly acknowledged and its effects are distinctive because: (1) TMFs often have very low rates of productivity due to low resources, and so recovery from disturbance may be slow, (2) montane forests have marked environmental heterogeneity which interacts with disturbance, (3) a large percentage of TMFs are regularly exposed to high energy windstorms and landslides, and (4) TMFs contain a biogeographically rich mixture of tree species with divergent evolutionary histories that interact differently with different disturbance types. We reviewed the literature on natural disturbance in TMFs and found 119 peer-reviewed papers which met our search criteria. Our review shows that disturbance is widespread in TMFs with pronounced effects on structure, function, composition and dynamics. Disturbance is also evident in the ecology of TMF biota with clear examples of plant life-history traits adapted to disturbance, including disturbance-triggered germination, treefall gap strategies and resprouting ability. Important aspects of TMF disturbances are stochastic and site-specific, but there are broad patterns in disturbance type, frequency and severity along latitudinal, altitudinal and environmental gradients. Compared with the lowland tropics, TMF disturbances are more spatially structured, TMFs experience more disturbance types in a given area due to environmental complexity, and TMFs are much more prone to small-scale yet severe landslides as well the large and potentially catastrophic disturbances of cyclones, forest die-back and fire. On the whole, natural disturbance should assume a larger role in models of ecosystem processes and vegetation patterns in TMFs. An improved understanding of what creates variation in disturbance severity and post-disturbance recovery rates, how composition and diversity feedback on disturbance type and likelihood, and how global change will alter these dynamics are important priorities in future TMF ecology research.

Abstract:

Indomethacin is a non-steroidal anti-inflammatory and antipyretic agent. Because different packing arrangements of the same drug can greatly affect drug properties such as colours, solubility, stability, melting point, dissolution rate and so forth, it is important to predict its polymorphs. The computational prediction of the stable form will reduce undesirable risks in both clinical trials and manufacturing. Reported polymorphs of indomethacin include α, β, γ, δ, ε, η and ζ [1], of which only the thermodynamically stable form γ and the metastable form α are determined. Density functional theory with dispersion-correction (DFT-D) has been used extensively to study molecular crystal structures[2]. It gives better results with a compromise between the computational cost and accuracy towards the reproduction of molecular crystal structures. In the fourth blind test of crystal structure prediction in 2007, the DFT-D method gave a very successful result that predicted all four structures correctly. Rather than using transferable force fields, a dedicated tailor-made force field (TMFF) parameterised by DFT-D calculations[3] is used for every chemical compound. The force field is used to generate a set of crystal structures and delimit a candidate window for energy ranking. The powder diffraction patterns of predicted polymorphs are calculated to compare with experimental data.

We begin by present a new Hopf algebra which can be used to compute the tmf homology of a space or spectrum at the prime 3. Generalizing work of Mahowald and Davis, we use this Hopf algebra to compute the tmf homology of the classifying space of the symmetric group on three elements. We also discuss the E3 Tate spectrum of tmf at the prime 3. We then build on work of Hopkins and his collaborators, first computing the Adams-Novikov zero line of the homotopy of the spectrum eo4 at 5 and then generalizing the Hopf algebra for tmf to a family of Hopf algebras, one for each spectrum eop_l at p. Using these, and using a K(p - 1)-local version, we further generalize the Davis-Mahowald result, computing the eop_1 homology of the cofiber of the transfer map [...]. We conclude by computing the initial computations needed to understand the homotopy groups of the Hopkins-Miller real K-theory spectra for heights large than p- 1 at p. The basic computations are supplemented with conjectures as to the collapse of the spectral sequences used herein to compute the homotopy.

Abstract:

The search continues for an environmentally safe, low cost, fast acting insecticide formosquitoes. Mosquitoes have been the cause of large-scale epidemics, such as yellowfever, dengue fever, and dengue hemorrhagic fever over the centuries. Even now, due tothe increase in the Aedes aegypti population, the threat still exists. In this research, six of nine compounds were synthesized as potential analogs of the decapeptide TMOF(trypsin modulating oostatic factor), which has already been identified as a growthinhibitor in mosquitoes. The nine compounds were derived from three different startingmaterials and six were completed in eight or fewer steps. These compounds were tested for larvacidal activity by feeding studies using Aedes aegypti. The compound 7-(3,4-dimethoxyphenyl)-4-heptenoic acid resulted in the lowest LC50, 0.62mM.

The algebraic structure of the K-theory of a topological space is described by the more general notion of a lambda ring. We show how computations in a lambda ring are facilitated by the use of Adams operations, which are ring homomorphisms, and apply this principle to understand the algebraic structure. In a torsion free ring the Adams operations completely determine the lambda ring. This principle can be used to determine the K-theory of an infinite loop space functorially in terms of the K-theory of the corresponding spectrum. In particular we obtain a description of the K-theory of the infinite loop space tmf in terms of Katz's ring of divided congruences of modular forms. At primes greater than 3 we can also relate this to a Hecke algebra.

Abstract:

The main objective of the work presented in this Licentiate of Engineering thesis is to investigate and model the fatigue crack propagation behaviour of the nickel-based superalloy Inconel 792, with special attention to the industrial lifing of high-temperature components. In-phase (IP) crack propagation tests have been performed at different temperatures and loading regimes, including extended hold times. The observations from these tests have been the basis for establishing several hypotheses to describe the crack growth behaviour, which progressively have been verified experimentally and numerically. Most prominently, it has been observed that crack closure has a substantial impact on crack growth and can explain, to a large degree, the crack growth behaviour for this material under the conditions studied. This phenomenon has been observed experimentally and modelled numerically to extend further the precision of the methodology.
Huvudsyftet med arbetet som presenteras i denna licentiat avhandling är att undersöka och modellera utmattnings sprickväxtbeteendet hos den nickelbaserade superlegeringen Inconel 792, med särskild uppmärksamhet riktad mot liuslängsdmodellering av högtemperaturkomponenter i en industriell kontext. I-fas (IP) sprickväxtprov har utförts vid olika temperaturer och belastningsregimer, inklusive hålltider. Observationerna från dessa tester har legat till grund för hypoteser för att förklara spricktillväxtbeteende, vilka successivt har verifierats experimentellt och numeriskt. Mest framträdande har det observerats att sprickslutning har en väsentlig inverkan på sprickväxten, och kan i stor utsträckning förklara sprickväxten för detta material under studerade förhållanden. Detta fenomen har observerats experimentellt och modellerats numeriskt för att förbättra metodens precision.

Abstract:

Materials need to be designed under certain conditions to withstand high thermal gradients to operate at high temperature environments. Many advanced gas cooled reactor (AGR) power plant components with operating temperatures in the range of 500-650 °C undergo creep-fatigue loading conditions. These components may be subject to isothermal low cycle fatigue (LCF) and thermo mechanical fatigue (TMF) damages due to the cyclic operation of power plant caused by the start-up and shutdown processes and due to the fluctuation of energy demand in daily operation. Hence, the influence of these cyclic loads induced mechanically and thermally, on the different structural components need to be carefully monitored and analysed in order to prevent failure and ensure safe operating conditions of critical units. The material Type 316 SS with cast number S7646, widely used in this type of components, is investigated in this project. The aim of this research is to conduct experimental tests to obtain quality stress-strain data for the material under investigation under cyclic plasticity in isothermal and an-isothermal tests using the available testing machine systems in the University of Imperial College London. The data obtained from experimental results are then utilised to develop advanced novel finite element damage models in a creep/fatigue loading environment in order to predict the cyclic behaviour under LCF conditions. Finally, the results of cyclic data derived from isothermal tests were used to predict the thermo mechanical fatigue behaviour for this alloy. The LCF-TMF testing unit, Instron 8801 with a temperature uniformity of less than ±10°C within the gauge section of the specimens were employed to conduct the experimental tests. Fully-reversed, strain-controlled isothermal tests were conducted at 500°C and 650°C for the strain ranges of ∆ɛ=±0.4%, ±0.8%, ±1.0% and ±01.2%. Strain-controlled in-phase (IP) thermo-mechanical fatigue tests were conducted on the same material and the temperature was cycled between 500°C and 650°C. Additionally, the creep-fatigue interactions were investigated with the introduction of symmetrical hold time at maximum strains in tension and compression under both LCF-TMF tests. From the investigation and the analysis of the experimental stress-strain data, three phases are observed when the cyclic stress responses are plotted; cyclic hardening, stabilisation and damage evolution. In the final stage of the behaviour of the material, a nonlinear decrease of the peak stress level was observed which was initiated by the presence of micro-crack and the failure occurred as the crack propagated. The evolution of inelastic strain energy density, ∆w, against the number of cycles, N, was used to determine the number of cycles at which the material stabilised, N_sta , the damage initiated, N_i and the failure occurred,N_f. The introduction of the hold time in both tension and compression strains in the LCF and TMF tests, produced an increase in the plastic strain range which subsequently increased the inelastic strain energy density and slightly reduced the peak flow stress when compared with the continues cyclic tests. The stress relaxation was observed when the hold time was introduced. The amount of stress relaxation was dependent on the test temperature and the imposed strain amplitude and the same trend was found when different strain ranges were examined. The cyclic behaviour of the Type 316 steel was further studied by analysing and performing microstructural investigations using the scanning electron microscope (SEM). The metallographic and the fractographic studies revealed that in all LCF-TMF tests the cracks mostly initiated in transgranular mode and propagated in either transgranular (under continuous cyclic loading) or in a mixed mode (under symmetric dwell period). The comparison of the metallographic and the fractographic studies of the LCF and TMF tests under both conditions (i.e. with and without dwell period) highlighted that the proportion of intergranular cracking increases with decrease in frequency, i.e. from 0.01Hz to 0.001Hz. Furthermore, the transgranular fatigue process dominates at high frequencies whereas the intergranular time dependent mechanism governs at low frequencies, low imposed mechanical strain amplitude and they both act together at intermediate frequencies and imposed mechanical strain amplitude. A constitutive model based on isotropic and nonlinear kinematic hardening rules was used to replicate numerically the cyclic structural behaviour of the material. A user-defined subroutine was developed and implemented in the finite element software, ABAQUS to predict the cyclic hardening, the stress relaxation during hold time and finally to demonstrate the damage evolution once the damage initiated. The final stage of the material behaviour (i.e. failure) was simulated numerically for both LCF and TMF tests conducted with and without hold time where for the tests with continuous cyclic loading (without hold time) a hysteresis energy-based phenomenological model was implemented in a USDFLD subroutine. Further, this model in combination with the creep damage model based on the time-fraction law were employed simultaneously to replicate the experimental results in which the hold time was introduced. In the end, the FE results were compared with the experimental results and the minor deviations observed in e.g. the first and stabilised hysteresis loops under TMF conditions or in the FE hysteresis damages, could be minimised by conducting further isothermal tests to define additional material properties at intermediate temperatures and performing tests at various strain ranges respectively.

Abstract:

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal – and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well. The unloading part of the cycle however cannot be described correctly by the use of this model.

It is a legal requirement for sponsors and investigators to maintain essential documentation. This chapter outlines the ICH GCP E6 requirements for documentation before, during and after the study. It describes each document and its purpose in the study. The chapter also describes how to deal with additional documentation kept by sponsors and sites but not addressed in the guidelines e.g. correspondence, emails and notes to file, The organisation of the trial master file (TMF) is not defined in guidelines but many companies and institutions will have a filing system described in SOPs, most are numeric and an example content list is given. The TMF must be maintained and stored correctly and version control of documentation is vital to maintain the audit trail. The legislation does not distinguish between commercial and non-commercial/academic studies but researchers are expected to adhere to the principles of GCP and maintain the TMF requirements. Originally TMF were paper based but the eTMF is now widely used by commercial sponsors. The retention time for the TMF has changed on a number of occasions the EU Regulation clearly states that essential documentation must be kept for 25 years and must be readily available for inspection.

Abstract:

International Trust Laws is a wide-ranging comparative guide to the law of trusts across a number of important jurisdictions, with analysis of issues surrounding the creation of trusts, the powers and duties of trustees, mechanisms of control, and the special uses of trusts. The book combines academic rigour and analysis with a practical focus on trusts in the real world, including assets which modern settlors wish to envelop in a trust; liability concerns of trustees; and the governance, command, and control mechanisms which increasingly form the largest feature of trust creation. It also provides valuable background for trust law practitioners, whether they advise on trusts, draft trust documents, or litigate trust-related matters. The new edition has been fully revised and updated to address important developments in case law and legislation, including the UK Supreme Court decision on the “rule in Hastings-Bass” (Pitt and Futter cases), the Privy Council decision on ‘reserved powers trusts’ (TMSF), decisions on forced heirship issues in Jersey and Guernsey, decisions on ‘asset protection trusts’ in the US, the Trusts (Amendment N. 5) (Jersey) Law 2012 and Trusts (Amendment N. 6) (Jersey) Law 2013, Hong Kong's Trust Law (Amendment) Ordinance 2013, the Virgin Islands Special Trusts (Amendment) Act 2013 and Trustee (Amendment) Act 2013, Cyprus' International Trusts (Amendment) Law 2012 Cayman Islands, Trusts Law (2011 Revision), and amendments to the trusts law of New Zealand. It also offers new coverage of the retirement, removal, and appointment of trustees, with a special emphasis on trustee indemnity; and the recognition of trusts in non-trust jurisdictions (civil law jurisdictions, Eastern Europe, Islamic countries, and China).

Abstract:

This chapter discusses the importance of archiving the data. As well as regulatory advice the requirements of the most useful reference guide, ISO11799, is reviewed. Practical advice on issues such as location, storage, security, and environmental controls is given. The management of the archive from preparation to transfer of data is described. Methods of indexing and cataloguing together with tracking are detailed and systems for retrieval of data are explored. The role of the archivist in audits and inspections is discussed as the content of the TMF will be assessed during audit to ensure a clear audit trail is maintained. Retention times for essential documents are reviewed in the EU the regulation stipulates that data has to be kept for 25 years. As more and more information has to be archived the use of off-site or commercial archives is becoming more common and the additional requirements for a third party service provider are described. The introduction of eArchiving and the associated problems with long term storage of electronic data are discussed along with the various methods that may be used. The FDA issued guidance for electronic data and compliance with this guidance, CFR21 part 11, is vital. CFR 21 part 11 is widely followed within Europe and the standard is frequently referred to by the regulatory inspectors.

Abstract:

<p>In this article, two new truss moment frame (TMF) systems exhibiting enhanced seismic performance are examined: truss moment frames with friction energy dissipation dampers between the truss bottom chord and the columns (F-TMFs) and F-TMFs with tendons added to achieve self-centering response (FT-TMFs). In both cases, all steel components of the systems are expected to behave essentially elastically to eliminate structural damage. The second system is also expected to have negligible residual lateral deformations. To compare and investigate the seismic performance of the proposed TMF systems, a 5-story commercial steel building located in Vancouver, BC, is designed in accordance with the National Building Code of Canada 2015 (NBCC) and it is subjected to a series of nonlinear static and dynamic time history analyses. The earthquake records, employed in non-linear time history analyses, are scaled for a hazard level corresponding to a probability of 2% in 50 years. The analytical results show that structural damage does not occur in neither of the two proposed systems . Meanwhile, FT-TMF system showed notably better seismic response and negligible residual deformations due to its self-centering capacity provided by the tendons.</p>

Abstract:

The design of turbine frames with turning vanes, known as turning mid-turbine frames (TMTF), becomes of great importance for high by-pass ratio engines with counter-rotating turbines. To achieve a more efficient low-pressure turbine the overall diffusion and radial offset should be increased. One goal of the EU project DREAM is to analyse the flow through a TMTF and a downstream arranged counter rotating LP rotor. The investigation of these complex interrelationships has been performed in the unique two-spool continuously operating transonic test turbine facility at Graz University of Technology. The test setup consists of an unshrouded HP stage, the TMTF and a shrouded LP rotor. The shafts of both turbines are mechanically independent, so the test rig allows a realistic two shaft turbine operation. The TMTF flow field is highly complex. It is a turbulent and unsteady flow dominated by strong secondary flows and vortex-interactions. The upstream transonic high pressure turbine stage produces a complex inflow with high levels of turbulence, stationary and rotating wakes and vortical structures. Therefore the application of advanced measurement techniques is necessary. To describe the HP-TMTF interaction time-resolved pressure measurements have applied within the project. The TMTF was instrumented with 10 fast response pressure transducers; static pressure tap recordings on the strut and on the TMTF end-walls have been also applied. Five hole probe, total pressure and total temperature rakes have been additionally acquired in the planes just in front of the struts and downstream to evaluate the performance of the TMTF. The results of these conventional techniques are presented in this work and they represent the necessary starting point for the evaluation and the description of the flow field. The idea is to start the study analysing the mean quantities and the overall performance of the two stages for different conditions and to leave the analysis of the time-resolved results for further investigation. Detailed investigations will start from the data presented in this paper; indeed, the use of unsteady measurement techniques is time consuming and cannot be performed for such a large amount of flow conditions, radial planes and HP vane - TMTF relative positions. Three operating conditions for different clocking positions have been considered. The variation of the operating conditions has been achieved by varying the HP shaft velocity and pressure ratio, with a consequence change of pressure ratio in the LP rotor. For this analysis the LP shaft velocity was kept constant. The TMTF performance variations will be analysed in terms of total pressure loss coefficient and exit flow angle; the mean interaction between the structures coming from the HP stage and the struts will represent the interpretation key to explain these variations. This work is part of the EU project DREAM (ValiDation of Radical Engine Architecture SysteMs, contract No. ACP7-GA-2008-211861).

Abstract:

Recent work within DDIT has shown that Ni base superalloys like HAYNES230, Co base superalloys like HAYNES188, super stainless steels like HAYNES HR-120, and stainless steels like 253MA are similar from a materials modelling point of view. They are austenitic, delivered solutioned, and precipitate secondary carbides and other brittle phases in service and during cyclic tests at elevated temperature. These new phases result in a significantly reduced RT ductility, while the high temperature ductility is at most moderately reduced. Therefore, TMF cycles, which repeatedly go down to low temperatures, see an embrittled alloy whereas LCF tests at Tmax (in the TMF cycle) do not. This suggests that the classical use of LCF data at Tmax might given non-conservative life estimates. Literature studies and materials testing have confirmed that TMF data may be well below LCF data at Tmax verifying the non-conservatism of the classical methodology. Furthermore, the cyclic life tends to decrease with decreasing Tmin in TMF tests, and IP TMF is usually more detrimental than OP TMF due to creep-fatigue interaction. While standard TMF tests are closer to reality than LCF tests, we are still not certain that they capture all detrimental effects under component cycling, and are running additional, carefully planned, TMF tests on aged specimen at low Tmin values to improve the analysis. More tests, especially biaxial IP TMF tests, will eventually be needed to get a comprehensive picture. A new TMF data backed model has, however, already shown a higher precision when compared with service experience than the classical creep-fatigue methodology which is calibrated with LCF data at Tmax. Further testing and analysis will enable us to refine the TMF model and extend it to additional ACP alloys. The main input to the TMF model is the stabilised inelastic strain range, as calculated by the constitutive model described in an earlier ASME Turbo paper, GT2002-30659.

Abstract:

The minimum film boiling temperature (TMFB) separates the unstable transition boiling region, where the liquid can contact the heated surface, and the post-CHF regime, where vapor can prevent the liquid from contacting the heated wall. This paper presents a review of minimum film boiling temperature correlations and describes a new technique to measure TMFB. The experiment proposed was simulated by TRACE and the same behavior was observed experimentally.
