Abstract:
During the process of cold forming of aluminum, the high pressure which is introduced on the die can result in high adhesion between the aluminum and the die surface. Therefore, it is necessary for the aluminum billet to be coated with a lubricant prior to forming, to reduce adhesion and to ease the flow of material in the die. There are several popular types of lubricant systems used in cold forging of aluminum. For severe deformation, conversion coating in conjunction with soap lubricant are commonly used. The conversion coatings include soap phosphates (PO4-soap), as well as soap aluminum fluoride (AlF-soap). Therefore, this work studied the performance of the AlF-soap system and compared it to the conventional PO4-soap system as tested on AA6063 aluminum. Ring compression tests and ball on disc tests were conducted to explore friction conditions and the thinning of the lubricant under several forming conditions. It was found that the quantity of metal soap layer of AlF-soap used affected the friction coefficient and the lubricant thinning under forming operation. The suitable coating weight of metal soap layer of AlF-soap for this experiment was found to be 2 g/m2. The friction coefficient of the PO4-soap system was 16.26% lower than the AlF-soap system. However, the amount of thinning of the AlF-soap film after ring compression tests was lower than that of PO4-soap film.

Abstract:
Lerak (sapindus rarak DC) is one of the plants that is often used as a noble metal washer, facial cleanser as a remover for acne and as an insecticide, especially earthworms. In this study the manufacture of soap gel by using Lerak plants. Lerak fruit (Sapindus rarak DC) is one of the natural ingredients that can be used as an alternative in soap raw materials. Lerak fruit (S. rarak) contains several secondary metabolites. The most dominant secondary metabolite is saponin. These saponins act as raw material for making soap. The purpose of this study is the use of natural materials, especially Lerak fruit as raw material for gel soap Tests conducted on soap are foam test, soap quality with experiments on several stains and organoleptic soap tests. The results obtained Lerak fruit can be used as raw materials for soap. The foam test results on the soap found that the soap foaming durability was longer. The results of soap quality testing on several stains namely charcoal stains, soy sauce stains and sauces prove the soap can clean stains well. The organoleptic results get a distinctive aroma, odor, and average of density are 1.01.

Abstract:
Divalent metal (barium, cadmium, calcium and zinc) soaps of rubber seed oil and their binary mixtures (Ba/Cd and Ca/Zn) and epoxidized rubber seed oil (4.5% epoxide content) and its admixtures with the single divalent metal soaps were evaluated as thermal stabilizer for dioctylphthalate plasticized PVC using changes in discolouration indices (yellowness index and UV absorption at 360nm) and initial rates of dehydrochlorination measured at 140 and 160oC. The results obtained showed that the divalent metal soaps were relatively effective in stabilizing the dioctylphthalate plasticized PVC against thermal degradation and that the binary soap mixtures enhanced the heat stabilizing effectiveness: marked reduction in the values of the discolouration indices; longer dehydrochlorination induction period and smaller values of rate constant of initial rate of dehydrochlorination. It was found that epoxidized rubber seed oil was less effective in comparison with the divalent metal soaps in stabilizing plasticized PVC against thermal degradation. These results show that the bio-based additives are compatible with dioctylphthalate plasticized PVC, stable to heat within the range of temperature used in the processing of plasticized PVC, inhibit/retard dehydrochlorination and reduce the extent of degradation.

Abstract:
Metal finishing plants, although the wastewaters and treatment schemes for this category are well defined, require a case by case evaluation to find appropriate solutions and to solve specific problems. In this paper, a case study conducted on a welding electrode plant is presented. The wastewater sources were surface cleaning, copper plating and soap solutions used for drawing which were frequently included in waters. The plant was subjected to pretreatment standards, which necessitated the control of sulfate and organic matter in addition to standard parameters of metals, oil, suspended solids etc. Following a source-based characterization, treatability studies were conducted to treat high concentration of sulfate, organic matter as well as heavy metals and oil-grease. The proposed treatment scheme involved separate treatment of copper bath for recovery, chemical oxidation for soap solutions, sulfate precipitation for sulfuric acid bath and application of hydroxide precipitation to proper combination of other wastewater sources.

Abstract:
Decarboxylation of metal soap is an emerging method to produce drop-in fuels as an alternative to the expensive hydrotreatment process. In this study, the Mg-Fe basic soap produced from palm kernel fatty acid had been successfully decarboxylated into jet-fuel type biohydrocarbons. The Mg-Fe basic soap with ratio of 8:2 mol was decarboxylated for 5 hours at atmospheric pressure and temperature varied up to 370°C; it produced a liquid product whose yield was around 60 %-weight. The resulting hydrocarbon product was a complex mixture consisted of normal paraffins in the range of carbon chain length C8 – C17, iso-and cyclo-paraffins, and various olefin products.

Abstract:
At the start of this project, the possible choices of metal soaps had already been narrowed to include some of the zinc soaps used in this project. These zinc soaps are mixtures of zinc stearate and zinc palmitate of varying ratios purchased from a supplier. Zinc soap was chosen as result of its common use in various industries as a lubricant and mold release, which implied potential benefits in an electrophotographic printing system. These potential benefits include, but are not limited to, a more efficient transfer from a photoconductive drum and protection of the drum from mechanical and chemical degradation. Nanoindentation of these soaps was implemented in an effort to characterize each soap mixture and compare how the soap types differed from one another. Each sample was indented under a variety of different maximum loads and at different holding times to observe effects on the modulus, hardness, and, creep. The mechanical properties measured were then used to help distinguish differences between each type and provide an insight as to how or why one mixture may be preferable over another. The data could be utilized in conjunction with further testing to be used in a simulation of an interface of interest.

Abstract:
In this thesis, geometry is used as a basis for conducting experiments aimed at growing and arranging inorganic minerals on curved interfaces. Mineralisation is directed using crystalline and liquid-crystalline metallic soaps and surfactant/water systems as templates.¶ A review of the history, syntheses, structure and liquid crystallinity of metallic soaps and other amphiphiles is presented as a foundation to understanding the interfacial architectures in mesostructured template systems in general.¶ In this study, a range of metallic soaps of varying chain length and cation type are synthesised and characterised to find potentially useful templates for mineral growth. These include alkaline-earth, transition metal, heavy metal and lanthanide soaps. These are systematically characterised using a variety of analytical techniques, including chemical analyses, x-ray diffraction (XRD) infrared spectroscopy (IR) and differential scanning calorimetry (DSC). Their molecular and crystal structures are studied using transmission electron microscopy (TEM), cryo-TEM, electron diffraction (ED), electron paramagnetic spin resonance (EPR), absorption spectroscopy (UV-VIS), high resolution laser spectroscopy, atomic force microscopy (AFM), nuclear magnetic resonance spectroscopy, scanning electron microscopy (SEM), electron dispersive x-ray analysis (EDXA), thermal gravimetric analysis (TGA) and magnetic measurements. Models for the molecular and crystal structures of metallic soaps are proposed. The soaps are predominantly lamellar crystalline or liquid crystalline lamellar rotor phases with tilted and/or untilted molecular constituents. These display evidence of varying degrees of headgroup organisation, including superstructuring and polymerisation. A single crystal structure is presented for a complex of pyridine with cobalt soap. Simple models for their structure are discussed in terms of their swelling properties in water and oils. Experiments are also presented to demonstrate the sorbent properties of aluminium soaps on oil spills.¶ The thermotropic liquid crystallinity of alkaline earth, transition metal, heavy metal and lanthanide soaps is investigated in detail. This is done to assess their suitability as templates, and to document their novel thermotropic behaviour, particularly the relatively unknown lanthanide soaps. Liquid crystalline behaviours are studied using high-temperature XRD (HTXRD), hot-stage optical microscopy and DSC. Models for a liquid crystalline phase progression from crystals to anisotropic liquids are discussed in terms of theories of self-assembly and interfacial curvature. The terminology required for this is drawn from various nomenclature systems for amphiphilic crystals and liquid crystals. General agreement with previous studies is reported for known soaps, while liquid crystallinity is demonstrated in the lanthanide and some non-lanthanide soaps for the first time. A general phase progression of crystalline lamellar through liquid crystalline lamellar to non-lamellar liquid crystalline is discussed in terms of models concerned with the molecular and crystal structures of the soaps and their phase transitions via headgroup and chain re-arrangements.¶ Experiments aimed at guiding growth of metal sulfides using metallic soaps as templates are described, and a model for this growth is discussed. Metal sulfides have been successfully grown by reacting crystalline and liquid crystalline transition metal and heavy metal soaps with H2S gas at room temperature and at elevated temperature. These have been characterised using XRD, TEM, ED and IR. Sulfide growth is demonstrated to be restricted and guided by the reacting soap template architecture. Zinc, cadmium, indium and lead soaps formed confined nanoparticles within the matrix of their reacting soap template. In contrast, curved and flat sheet-like structures, some resembling sponges were found in the products of sulfided iron, cobalt, nickel, copper, tin and bismuth soaps. A model to explain this behaviour is developed in terms of the crystal and liquid crystal structures of the soaps and the crystal structures of the metal sulfide particles.¶ Liquid crystalline iron soaps have been subjected to controlled thermal degradation yielding magnetic iron oxide nanoparticles. Some XRD and TEM evidence has been found for formation of magnetic mesostructures in heat-treated iron soaps. Models for the molecular and liquid crystalline structure of iron soaps, their thermotropic phase progression and eventual conversion to these magnetic products are discussed. Systematic syntheses of mesoporous silicates from sheeted clays are discussed.¶The templates that have been used are cationic surfactants and small, organic molecular salts. Experiments are reported where a cooperative self-assembly of surfactant/water/kanemite plus or minus salt and oils yields 'folded sheet materials' (FSM'S). Templating of kanemite has also been achieved using cobalt cage surfactants. A theoretical prediction of the specific surface areas and specific volumes of homologous sets of FSM's gave excellent agreement with measured values. The geometry and topology of the mesostructures are discussed. A theoretical model is also discussed regarding the curvature found in the sheets of natural clays , and results of templating clays and silica using metallic soaps are presented. Experiments and a model for low temperature nucleation and growth of microporous silicalite-1 are described in terms of silica templating by water clathrates.¶ Finally, the problem of finding minimal surface descriptions of crystal networks is addressed. Combinatoric methods are used to disprove the existence of possible embeddings of type I and II clathrate networks in non-self intersecting periodic minimal surfaces. The crystal network of the clathrate silicate, melanophlogite is successfully embedded in the WI-10 self-intersecting surface. Details of a previously unreported, genus-25 periodic surface with symmetry Im3m are discussed.

Abstract:
Very few stone sculptures conserve their original polychromy nowadays so the exceptional condition presented by the oil paint film of the Tomb of Chancellor Villaespesa in the Cathedral of Tudela (Spain) here presented as case study suggested that both the chemical-mineral composition of the oil paint films and of the lithotypes chosen for the artists to be in contact with the polichromy, could be responsible for their unexpected durability. When the mechanisms governing these painted structures stability are not understood properly, conservation materials and methods and even environmental conditions can have a dramatic effect in their performance and compromise their stability in the long term. In this study, mock-ups simulating different oil paint layers on the sandstone of the case study have been prepared. Mock-ups with the same oil paint films on other substrates have been made for comparison purpose. After four years of natural ageing, the aggregation of lead and calcium carboxylates have been identified and characterized on some mock-ups by means of the combined use of UV-VIS light microscopy, SEM-EDX and micro FT-IR spectroscopy. pH and conductivity have been measured and monitorized both in the mock-ups and the case study. Saponification reactions, ionomer formation and carboxylate aggregation in lead white or minium oil paint films contributed to make them less acidic, less ionized, less hydrolyzed and less soluble after ageing sandstone or on pine wood at room environmental conditions for four years. The same given paint films became more acid and more ionized after ageing on a glass slide. Understanding the properties of such films, the chemical-physical mechanisms governing their adhesive and cohesive forces, and their surface pH is not easy. Mineral assemblages as well as the availability of ions in the substrate of a given oil paint film containing lead white or minium play a fundamental role in the eventual formation, migration and aggregation of lead and calcium carboxylates not only at their surface but also within the substrate-film interface. Furthermore, monitoring surface pH and conductivity as well as understanding solubility issues and the adhesion forces existing between soils, the paint layer and the substrate is needed when designing any conservation strategy to minimize risks and to preserve the balance acquired by these artworks in time.
Muy pocas esculturas pétreas conservan su policromía original. El excepcional estado en el se mantienen las películas pictóricas al óleo del caso de estudio de esta tesis doctoral (el Sepulcro de Villaespesa de la catedral de Tudela, Navarra, España) sugiere que tanto la composición químico-mineral de la roca seleccionada por sus escultores como la composición de las películas pictóricas al óleo con las que se policromó dicha piedra, podrían ser responsables de su inesperada durabilidad. En el transcurso de esta tesis doctoral se prepararon probetas con distintas películas pictóricas al óleo sobre la arenisca del caso de estudio. Para hacer un análisis comparativo también se prepararon probetas con las mismas películas sobre otros soportes. Se monitorizó el pH y la conductividad el caso de estudio así como de todas probetas. A través del uso combinado de microscopía óptica, SEM-EDX y micro espectroscopía FT-IR se estudió la formación y envejecimiento de las películas al óleo identificó y se caracterizó la agregación de carboxilatos de calcio y plomo en algunas de las películas pictóricas al óleo con pigmentos de plomo. En aquellas películas al óleo con albayalde o minio que envejecieron durante cuatro años sobre substratos de arenisca y madera de pino, las reacciones de saponificación, la formación de ionómeros y la agregación de carboxilatos contribuyeron a generar estratos pictóricos menos ácidos, menos ionizados, menos hidrolizados y menos solubles. Dichas películas pictóricas se tornaron más ácidas e ionizadas tras envejecer, en las mismas condiciones medioambientales, sobre vidrio de microscopio. La comprensión de los mecanismos físico-químicos que gobiernan no solo el pH y la conductividad sino también las fuerzas adhesivas y cohesivas de estas películas a lo largo del tiempo, no es sencilla. Tanto los agregados minerales como la disponibilidad de iones que presentan sus substratos juegan un papel fundamental en la eventual formación, migración y agregación de carboxilatos de calcio y plomo no solo en su superficie, sino también en la interfase substrato-película pictórica. Cuando los mecanismos que gobiernan los equilibrios físico-químicos de estos sistemas pictóricos no se comprenden adecuadamente, los materiales y métodos empleados en su conservación así como las condiciones medioambientales en las que se mantienen pueden tener un efecto dramático en el comportamiento de estos sistemas pictóricos y comprometer su estabilidad a largo plazo.
Molt poques escultures pètries conserven la seua policromia original. L'excepcional estat de conservación en que es conserven les policromies del cas d'estudi d'aquesta Tesi Doctoral (el Sepulcre de Villaespesa de la catedral de Tudela, Navarra, Espanya) sugereix que tant la composició química-mineral i la porositat de les roques seleccionades pels artistes com la composició de les pel·lícules pictòriques a l'oli que van preparar per a policromar la pedra, podrien ser responsables de la seua inesperada durabilitat. Quan els mecanismes que governen els seus equilibris fisicoquímics no han estat compresos adequadament, els materials i mètodes emprats en la seua conservació així com les condicions mediambientals en què es mantenen poden tinder un efecte dramatic al comportament d'aquests sistemes pictòrics i comprometre la seua estabilitat a llarg termini. En aquesta tesi es van preparar provetes amb diferents pel·lícules pictòriques a l'oli sobre l'arenisca emprada en el cas d'estudi. També es van preparar provetes amb les mateixes pel·lícules sobre altres suports per fer una anàlisi comparatiu. Després de quatre anys d'envelliment natural, es va identificar i caracteritzar l'agregació de carboxilats de calci i plom en algunes de les provetes a través de l'ús combinat de microscòpia òptica, SEM-EDX i micro espectroscòpia FT-IR. També es monitarizaren el pH i la conductivitat de les provetes així com del cas d'estudi. En aquelles pel·lícules a l'oli amb blanc de plom o mini que van envellir durant quatre anys sobre substrats de gres i fusta de pi, les reaccions de saponificació, la formació de ionómeros i l'agregació de carboxilats van contribuir a generar estrats pictòrics menys àcids, menys ionitzats, menys hidrolitzats i menys solubles. Aquestes pel·lícules pictòriques es van tornar més àcides i ionitzades després envellir, en les mateixes condicions mediambientals, sobre vidre de microscopi. La comprensió dels mecanismes fisicoquímics que governen el seu pH i la seua conductivitat així com les forces adhesives i cohesives d'aquestes pel·lícules al llarg del temps no és senzilla. Tant els agregats minerals com la disponibilitat de ions que presenten els seus substrats juguen un paper fonamental en l'eventual formació, migració i agregació de carboxilats de calci i plom no només en la seua superfície, sinó també en la interfase substrat-pel·lícula pictòrica.

Dissertação para obtenção do Grau de Mestre em Conservação e Restauro
This project involved the conservation of a 19th century portrait in oils from the Ecomuseu do Seixal (Portugal). The painting of “João Luiz Lourenço” was in very poor condition. Because of the range and severity of the problems presented, it offered an opportunity to explore important aspects of painting conservation in-depth. The approach to its treatment required an empirical investigation of a number of materials and techniques used in the field of conservation/restoration. Of additional interest, the painting exhibits widespread evidence of metal soap (lead carboxylate) aggregates protruding through the paint from the ground layer. The painting’s materials and the metal soaps aggregates were studied and characterised with different analytical techniques: μ-EDXRF (Energy Dispersive X-ray Fluorescence), μ-Raman Spectroscopy, μ-FTIR (Fourier Transform Infrared Spectroscopy) and SEM-EDX (Electron Scanning Microscopy with Energy Dispersive X-ray Spectroscopy). Part 1: describes the study of the materials and the technique of the painting, and of the metal-soap aggregation within the painting’s ground layer. Observation with the Optical Microscope and with SEM-EDX of paint/ground cross-sections reveals the presence of two visually distinct lead carboxylate aggregates: one, completely white, and the other with a white centre surrounded by distinct red particles identified as red lead (minium: Pb3O4) by μ-Raman. The presence of these two types raises questions about whether there are different starting materials for the aggregates or whether they could be in different states of evolution. Part 2: describes the design and implementation of the conservation/restoration treatment. The treatment of the painting raised challenges and at various stages involved the exploration of non-traditional methods. At every stage during the treatment the consequences of an intervention was carefully considered in relation to the subsequent steps. All decisions were taken according to the painting’s intrinsic conservation problems and materials and with regard to the future environment of the painting.

Abstract:
The potential for stigmatising public attitudes to have a negative impact on the wellbeing of individuals identified as experiencing mental distress has been widely documented. The contribution of the mass media towards public attitudes surrounding mental distress has attracted particular interest, particularly that of television portrayals. Research into the influence of the media towards public attitudes has focused on a ‘strong media’ model that assumes a direct influence of the content on viewer attitudes. Recent theory has suggested an ‘audience response’ model whereby audience attitudes towards the subject matter, genre and purpose of viewing can influence their understanding of the content; however this approach is under-represented in research. In the United Kingdom the soap opera genre in particular is positioned to have a potential role in influencing public attitudes towards mental distress, frequently depicting mental distress within a realist frame and being presented as having a public service function. This thesis aims to explore the ideas that viewers take from soap opera portrayals of mental distress within an audience response approach. Soap opera viewers were interviewed about the ideas of mental distress they developed from storylines they had watched, and these interviews were analysed using a discursive thematic analysis, taking into account their beliefs about mental distress, the soap opera genre and their viewing purposes. These constructions drew attention to the presentation of mental distress as socially undesirable and incomprehensible, the validation of mental distress storylines as socially responsible by programme makers and viewers, and the purpose of these storylines as cautionary tales against dissent from professional opinion. This research supports calls for greater diversity in television representations of mental distress; in particular a stronger representation of positive or heroic qualities in characters portrayed with mental distress, and a greater role for psycho-social explanations of their distress. This research also questions whether positive representations of mental distress are best served through explicit ‘anti-stigma’ campaigns.

Abstract:
La séparation des préoccupations permet de considérer les sous-systèmes en isolation tout en conservant une vision globale du système. La variabilité des domaines impliqués implique donc (i) un effort de composition des méta-modèles hétérogènes représentant ces domaines, (ii) une gestion de la cohérence inter-domaine des modèles produits en isolation et (iii) une gestion de la multiplicité des cibles atteignables dans l'espace des solutions de chacun des domaines. Pour relever ces défis, nous présentons dans cette thèse une approche couvrant trois contributions appliquées sur le cas de la visualisation de données :- une approche de composition respectant l'isolation des domaines en tirant profit des méthodes d'intégration des Architectures Orientées Services (SOA). Les méta-modèles sont encapsulés dans des services, exposant le comportement pertinent via une interface à destination des experts du domaine ;- un moteur de règles métiers qui assure la gestion des interactions entre domaines et permet de détecter les incohérences inter-domaine et de faire remonter aux experts les informations nécessaires à leur résolution ;- une modélisation de la variabilité des produits par caractérisation qui permet de concrétiser les sous-systèmes vers des artefacts concrets.Pour valider l'approche, nous quantifions (i) le surcoût de l'encapsulation en service des domaines, (ii) l'impact de l'externalisation des interactions entre domaines, (iii) l'effort que les experts et l'intégrateur doivent fournir. Enfin, une expérience utilisateur mesure le gain lors de la concrétisation du système et son impact sur la satisfaction vis à vis des visualisations résultantes
The growing complexity of software engineering leads to the use of separation of concerns, i.e. enable to consider manageable sub-systems while keeping an overview of the whole system. The domain variability involved in these system design imply : (i) to compose multiple heterogeneous metamodels dedicated to each domain, (ii) to handle cross-domain consistency of the model produced in isolation, (iii) and to tame the multiplicity of concrete artefact available in the solution space of each domain. To adress these challenges, we offer in this thesis an approach encompassing three contributions :- an isolation-compliant composition which benefits from Service Oriented Architecture (SOA) integration. Each domain metamodel is embedded in a service exposing the rele- vant behavior through an interface designed and used by domain experts ; - a business rule engine handling the interaction between domains and detecting cross-domain incon- sistency to provide relevant feedback to resolve it ;- a feature-based characterization of the products variability allowing to concretize each sub-system toward concrete artifacts. The contributions are applied on the sensor data visualization use case.We validate (i) the need for domain isolation preservation on a dashboard design project, then we quantify (ii) the overhead of the service encapsulation, (iii) the impact of the externalization of domain interactions, (iv) the effort required from the experts and the integrator. Finally, we proceed to a user experiment to measure the gain during the concretization of a sub-system, and the impact on the user satisfaction on the resulting visualisation widgets

Abstract:

Battletank crew must perform many diverse tasks during a normal mission: Crewmembers have to navigate, communicate, control on-board systems, and engage with the enemy, to mention a few. As human processing capacity is limited, the crewmembers will find themselves in situations where task requirements, due to the number of tasks and task complexity, exceed their mental capacity. The stress that results from mental overload has documented quantitative and qualitative effects on performance; effects that could lead to mission failure.

This thesis describes a simulation of tankcrew during a mission where mental workload is a key factor to the outcome of mission performance. The thesis work has given rise to a number of results. First, conceptual models have been developed of the tank crewmembers. Mental workload is represented in these models as a behavior moderator, which can be manipulated to demonstrate and predict behavioral effects. Second, cognitive models of the tank crewmembers are implemented as Soar agents, which interact with tanks in a 3D simulated battlefield. The empirical data underlying these models was collected from experiments with tankcrew, and involved first hand observations and task analyses. Afterwards, the model’s behavior was verified against an a priori established behavioral pattern and successfully face validated with two subject matter experts.

Abstract:
Reflow parameters during assembly are ramp rate, soak time, soak temperature, peak temperature, time above liquidus, and cooling rate. These reflow parameters constructs the temperature profile of reflow process and determine the quality of interconnects in the electronics products. To investigate the effect of reflow parameters on solder interconnect wetting, the wetting rate of a single liquid solder sphere on a metal substrate with variation of reflow parameters were experimentally measured and the constitutive model for the dynamics of solder wetting was suggested.

Abstract:
Prototype, low power, high rate resistance heaters for temperature programming metal micro gas chromatograph (GC) separation column chips were fabricated using UV lithography. Spin coated polyimide was used as the electrically insulating layer between the heating coil and the GC column chip because of its excellent thermal properties — in particular the ability to match the coefficient of thermal expansion with nickel and copper, and ease of application. Low resistivity, copper and nickel, metal heating elements were electrodeposited directly on the polyimide layer spin coated on top of the nickel GC column chips. In experiments, the microfabricated heaters were able to heat the GC column at rates from 5°C/sec to 50°C/sec under PID control. Temperatures from 125°C to 250°C were maintained for soak times of up to 30 seconds. The heaters can be used to generate a variety of temperature programming profiles and offer flexibility in selecting the different ramp rates and soak temperatures needed for different applications.

Abstract:
This paper presents a discussion of heat soak-back for various gas turbine engine shutdown scenarios, compares with experimental data and discusses how the temperatures at the shutdown point can be used to approximately determine a suitable shutdown procedure for ambient and hot ambient conditions in order to control the bearing soak back peak. The investigation was performed by running the test vehicle at various engine conditions and shutdown procedures while measuring the temperatures at the bearing outer tracks. The data acquisition continued after the engine shutdown until the temperature data showed that the soak-back peak temperature had passed. The tested engine conditions were replicated in a FEM model of the turbine, from which knowledge was gained of the turbine discs temperatures during the shutdown and subsequent cooling down. It was shown that the bearing soak-back and cooling down after shutdown is determined by the cooling down of the turbine discs. The discs are directly affected by the blade temperature reduction, which in turn is depending on how the air trapped in the main gas annulus after the engine has stopped rotating is cooling down. The cooling down of the main annulus air is due to free convection and conduction to the surrounding metal, and cannot be readily predicted with current tools (the air is not moving). Therefore, an approximation of the temperature behaviour is needed. It was decided for the present study to investigate the correlation between the disc temperature at the shutdown point with the bearing soak-back peak temperature and time. It was found that the disc rim temperature at the shutdown point could be used to determine an approximate soak-back peak and thereby the need for motor-overs (MO). The conclusions are that various shutdown procedures and motor over cooling can be used in order to extend the engine operability without expensive bearing redesign.

Abstract:
Um Sistema-de-Sistemas (SoS) é uma classe de sistema caracterizada pela união de sistemas constituintes que são independentes no modo operacional e gerencial e que juntos desempenham novas funcionalidades. Devido as suas características de evolução e interopelabilidade, os SoS são amplamente usados em diversos contextos críticos como gestão de desastres, sistemas de cuidados com a saúde, sistemas militares e cidades inteligentes. Um processo arquitetural de SoS visa definir os stakeholders, sistemas constituintes e como eles interagem entre si e os comportamentos emergentes produzidos por essas interações. Todos esses elementos são definidos a partir de um entendimento do contexto por meio da engenharia de requisitos, descrição da arquitetura e da modelagem das visões arquiteturais do sistema. Pesquisas recentes mostraram poucos avanços no estudo de processos arquiteturais nessa classe de sistema e nesse sentido pesquisas são necessárias para atender às demandas encontradas na literatura para o projeto, análise, avaliação e evolução de arquiteturas em SoS. Com base nisso, esta pesquisa apresenta o PASoS (Processo para definição da Arquitetura de Sistemas-de-Sistemas), um processo criado para ser uma instância do meta-processo SOAR ("Meta-process for SoS Software Architectures") que visa definir por quais elementos um processo arquitetural em SoS deve ser composto. Para isso, em trabalhos futuros os elementos essenciais do SOAR (Alpha e espaços de atividades) serão generalizados em três fases do PASoS, onde em cada uma delas serão elencados sequencialmente os espaços de atividades definidos pelo SOAR que no PASoS são responsáveis por produzir os artefatos arquiteturais (Alphas do SOAR). Espera-se que essa instância de processo oriente os arquitetos de SoS na sequencia de etapas necessárias para construção da arquitetura do SoS para contextos críticos.

Abstract:
Modern Gas turbine efficiency increase accompanied by higher turbine inlet temperature, pressure levels and rotor speeds. These demands an accurate thermal analysis of bearing compartments as large load transferred through bearings and heat load from surrounding environment. Two phase flow air &oil) is common in bearing compartments and it makes heat transfer coefficient estimation a difficult task. Bearing friction, oil churning, seals heat generations and heat input from the surroundings need to be considered accurately to predict the compartment temperatures at various operating conditions. In addition to analysis for operating conditions, bearing compartment soak back analysis is also critical for safe operation of bearings. Absence of oil flow during shutdown of the engine can cause coking of oil film due to heat soak from the hot surroundings. Accurate soak back analysis is therefore required to simulate the thermal response of the bearing compartment during shutdown. For the normal operating conditions, detailed numerical investigations are carried out to predict (i) optimal oil flow rate at a given rotor speed, (ii) maximum rotor speed allowed for the specified oil flow rate and (iii) the heat transfer rates for various air fractions of the oil & air mixture. The results are validated against available Engine data on scavenge oil and bearing race metal temperatures.
