Fabric deformation properties considerably depend on its structure. Garment elasticity is an important factor that allows a garment wearer to move freely. Fabric deformation depends on the structure parameters of yarrn and fabric. It has been known that elongation at break of fabric with elastane yarn is higher than of ordinary fabric. The aim of this work was to analyse elongation at break parameters of the and warp and weft yarn in fabrics. Ten commercially produced samples of woven fabrics were used in the experiment. Some samples were with elastan yarn in the warp and weft directions or only in the weft direction. Elongation at break was measured applying a standard method. The results showed that elongation at break of the main elastic component or another component may occur simultaneously when an elastic component or elastane yarn may reach fabric ultimate elongation.

Now the Mechanical Properties of fabrics is widely studied, but always involve in one kind of fabric or a certain property. In order to further understand the fabric tearing strength comprehensively, through a lot of experiments, this article mainly study the single or multiple influences of warp and weft fineness, warp and weft density, warp and weft yarn strength, break elongation of warp and weft yarn, fabric thickness of five fabrics on single stitch tearing strength and trapezoid tearing strength. Then we use SPSS statistical analysis tools to conduct multiple linear regression analysis. We can conclude that warp and weft tightness of fabrics, warp yarn strength, elongation at break of weft yarn have the influence on tearing strength; When trapezoid Angle is changed from 27 degrees to 45 degrees, the influence of warp and weft tightness on it will become bigger, but the influence of warp yarn strength, elongation at break of weft yarn on it will become smaller, and so on.

Ultrasonic seam strength and elongation at break properties of thermal bonded nonwoven fabrics are discussed in this study; and the effects of fiber type, fabric area density, and roller type on ultrasonic tensile properties of nonwoven fabrics are reported. Polypropylene (PP), Polyester (PES), and Polyamide – Polyester (70% PA - 30%PES) blend of thermal bonded nonwoven fabrics were used, and the seam strength and elongation at break were measured and the obtained data were evaluated. At the end of the experimental studies, the data from the ultrasonic tensile properties of thermal bonded nonwoven fabrics which were made of different fibers and same production method were evaluated in order to determine the tensile properties which lead to the best result. The experimental results show that the PP thermal bonded nonwoven fabric tended to provide the best seam strength and elongation at break values.

Polypropylene (PP) spunbond nonwoven fabrics are very important especially for health, furniture, and household industries. These industrial applications require fabrics with high tensile strength properties. In the textile industry, Digital Image Analysis (DIA) is used commonly on fabric property determination and online controlling. The estimation of fabric weight using digital image analysis is well established in the literature. But limited information can be found about the prediction of grab tensile strength and elongation at break using Digital Image Analysis (DIA). In this study, DIA and Artificial Neural Network (ANN) are used for the prediction of areal weight, tensile strength and elongation at break values of PP nonwoven fabrics at various weights (12g/m2, 20g/m2, 25g/m2, 30g/m2, 50g/m2). The experimentally tested fabric properties and the numerical defined statistical parameters obtained from DIA are related with each other using ANN. Results show that ANN is capable of prediction of fabric material properties by using data obtained by DIA without any experiments for the investigated type of PP nonwovens.

Coated fabrics have complex composite structure whose mechanical properties are considerably improved in relation with the initial basic material. They are obtained by applying a certain number of coatings to raw fabrics. In this paper the practical application of uniaxial testing of coated fabrics for determining its breaking properties and Poisson’s ratio is presented. Due to the anisotropy of woven and coated fabrics, Poisson's ratio changes over the fabric sample stretching. Experimental testing were carried out on two samples of plain weave cotton fabrics. The fabrics were tested before coating, and after one, two and three coatings. Samples are stretched with tensile force in the weft and warp direction, and based on different measured values of fabric stretching, warp and weft Poisson's ratio is calculated. The values of tensile force and relative extension of coated fabrics were measured, and breaking force values, elongation at break, contractions at break.

Abstract Key importance and the role of sewn seam in the woven fabric are presented. Fabric properties in the places joined with the sewn seam on which garment durability, applicability, appearance and quality depend are highlighted. Seam location is usually the weakest spot on the garment, especially when the great loads are present at these places. Mechanical properties of the sewn fabrics were investigated in different test conditions. The influence of the load on the sewn seam is analyzed in time intervals. Sample with seam have approximately 70% lower breaking properties (breaking force and elongation at break) than the sample without seam. By preloading the seam fabrics with 30%, 50% and 70% of elongation at break, for a 3-h period, the effect on mechanical properties were tested and the differences in pre-stretching intensity were observed. By conducting such test, it is expected that the fabric experience further degradation and that breaking properties further reduce, but the exact opposite occurred (breaking properties, by increasing the preload, increase even more), because of various material properties (structural fabric properties, raw material characteristics, seam characteristics).

Abstract The main parameters of tensile tests for fabrics and yarns are the breaking force and the elongation at break. The aim of this investigation was to find the relation between the tensile properties of yarns and woven fabrics for different natural raw materials. Manmade bamboo, natural single flax, blended plied flax and natural silk yarns, plied combed cotton yarns, blended plied cotton, and polyester yarns were used for the research. The warp of almost all fabrics, except of one fabric, was from flax. This fabric was woven using blended flax and silk yarns in the warp. Weft yarns were more various – yarns of one kind were used in the weft for certain fabrics; yarns of two kinds were used in 1:1 repeats in other fabrics. It was established that the breaking force for both woven fabrics and yarns increases when the elongation at break increases. The relationships between the tensile parameters of yarns and woven fabrics were established. The results showed weak dependence between the tensile parameters of yarns and fabrics because the coefficients of determination of the dependences are small.

The behaviour of textile products made from different fibres during finishing has been investigated by many scientists, but these investigations have usually been performed with cotton or synthetic yarns and fabrics. However, the properties of raw materials such as linen and hemp (other cellulose fibres) and linen/silk (cellulose/protein fibres) have rarely been investigated. The aim of the study was to investigate and compare the mechanical (breaking force and elongation at break) and end-use (colour fastness to artificial light, area density, and abrasion resistance) properties of cellulose and cellulose/protein woven fabrics. For all fabrics, ΔE was smaller than three, which is generally imperceptible to the human eye. Flax demonstrated the best dyeability, and hemp demonstrated the poorest dyeability, comparing all the tested fabrics. The colour properties of fabrics were greatly influenced by the washing procedure, and even different fabric components of different weaves lost their colours in different ways. Flax fibres were more crystalline than hemp, and those fibres were more amorphous, which decreased the crystallinity index of flax in flax/silk blended fabric. Unwashed flax fabric was more resistant to artificial light than flax/silk or hemp fabrics. Finishing had a great influence on the abrasion resistance of fabrics. The yarn fibre composition and the finishing process for fabrics both influenced the mechanical (breaking force and elongation at break) and end-use (area density and abrasion resistance) properties of grey and finished fabrics woven from yarns made of different fibres.

This study deals with two different categories of needle-punched nonwoven fabric samples developed from virgin and recycled polyester fibers. To understand the effect of tensile behavior (strength and extension) of these filters, fabric samples have been developed varying fabric weight, needling density and depth of needle penetration. This study also established the efficacy of use of recycled polyester for preparation of filter fabric. The study revealed that the tensile strength of fabric made using recycled fiber is 8–10% lower compared to virgin. Tensile strength is more in cross direction as compared to machine direction for both virgin and recycled polyester fabrics due to the higher number of fibers oriented in cross direction during cross lapping process. Increase in needling density and depth of penetration has resulted in increase in the extent of tensile strength initially but decrease in the extent of tensile strength later in all the cases of fabric weight. The study further reveals that heavy weight fabric, needling density and depth of penetration results in decrease of elongation at break (%). The elongation at break (%) of fabric prepared from recycled fiber was found to be 7–8% higher in machine as well as in cross direction compared to virgin. Since strength parameter is not very essential in case of filter fabric made of recycled polyester, which is lesser in strength (8-10%) compared to virgin polyester may be considered.

This study investigates the properties of polylactic acid (PLA) multifilament and its warp-knitted fabrics. Multifilament properties were tested and compared with PET multifilament with different diameters. The 83.3 dtex PLA multifilament was used to knit the fabric, and the fabric properties before and after dyeing were studied. Results showed that the mechanical properties of PLA multifilament were comparable to those of PET. However, PLA had a higher heat shrinkage rate. The dyed PLA warp-knitted fabric has excellent color fastness. Due to the influence of temperature and dye particles during the dyeing process, the breaking strength, air permeability and moisture permeability of the fabric were decreased. On the contrary, the elongation at break, abrasion resistance, anti-pilling properties, drape and crochet value of the fabric were increased.

MicroElectroMechanical Systems, or MEMS, is an emerging high technology that has proven to be very successful in several industries such as medical, automotive and ink jet industries. The technology philosophy is to integrate sensors, actuators and electronics onto a silicon substrate (polysilicon batch) to form as small as a square millimeter micromachine at low manufacturing cost. Such advantages prompted investigating the potential applications of MEMS in textiles.Initially, we identified possible applications of MEMS technology in spinning, weaving, knitting, fiber formation, nonwovens, testing and evaluation, and dyeing and finishing. Based on a perceived real need and large potential market for a successful device, it was decided to concentrate efforts into the development of a MEMS based detection device to monitor warp tension and end breaks in weaving. Thus replacing the abrasive and passive traditional drop wire with gentle and active device that has the potential to expand the markets for weavers. A macro prototype device (sensors, software and hardware) to monitor warp tension and break was designed and built. Descriptions of the device components along with weaving specifics are given. To demonstrate the benefits of the device, several experiments were conducted. The experiments along with their results are reported. The experiments include: Simultaneously monitor tension of eight individual warp ends in real time  Identify complex weave patterns through matching tension fingerprint with weave floats and intersections Detect yarn tension trends while weaving Quantify variations of warp tension across beam width Identify variations of warp tension at the warp sheet edges Monitor the behavior of the warp let-off mechanism Detect broken warp yarns Assess warp yarn damage caused by using drop wiresBased on the results of these experiments, it can be concluded that monitoring individual warp yarn tension could provide a useful mean for woven fabric producers as well as weaving machine manufacturers. From these findings, the micromachine, an array of piezoresistive sensors, was designed and built.

Devido ao crescente aumento da percentagem da população mundial referente a indivíduos com idade igual ou superior a 65 anos, é pertinente a aposta no desenvolvimento de um produto que tenha como público-alvo a referida fração da população. Neste sentido, foi levado a cabo um processo de desenvolvimento de um pão de forma, não doce, com características nutricionais adequadas à dieta, condição física e de saúde médias, e tratamento/prevenção de doenças com maior representação na população idosa mundial. Paralelamente, efetuaram-se também estudos relativos à aferição das consequências que duas estirpes de leveduras não comerciais têm, no pão desenvolvido, relativamente às suas características organoléticas. Compararem-se os resultados com os de uma estirpe comercial utilizada em produção industrial, sendo que para tal se procedeu à realização de provas sensoriais com grupos de provadores não treinados. De modo a obter as quantidades necessárias das duas leveduras não comerciais utilizadas, efetuou-se o crescimento em laboratório a partir de culturas iniciais. Os resultados das provas sensoriais indicam que as leveduras não comerciais não podem ser consideradas preferíveis à levedura comercial, uma vez que não são conclusivos. Especificamente, considerou-se que as diferenças entre amostras, respetivamente, nas duas provas efetuadas, não foram significativas, o que faz com que a levedura comercial (de produção normalizada, baixo preço, regularizada relativamente a legislação) se mantenha como mais favorável, para o caso estudado. Relativamente ao produto final produzido, conseguiram-se alegações nutricionais favoráveis, parte do objetivo inicial, segundo a legislação em vigor, tais como: “Alto teor em fibra”, “Baixo teor de gordura saturada”, “Baixo teor de gordura” e “Fonte de proteína”. Não foi possível tirar conclusões quanto ao teor em sais minerais, nem alegações nutricionais relativas a estes compostos. Tais alegações só podem ser aplicadas em rótulo mediante análise nutricional do produto, e validação das mesmas, por uma entidade certificada.
Due to the growing increase in the percentage of the world’s population concerning individuals who are 65 years old, or older, the development of a product which has, as its consumer target, this population fraction, becomes pertinent. In this project, the development of a bread loaf, non-sweet, with nutritional characteristics that are adequate to the diet, average physical and medical condition, and treatment/prevention of diseases that are most commonly present on the world’s elderly population, is described. Also, some studies that are related to the assessment of the consequences which two strains of yeast, non-commercial, have, on the bread that is to be developed, regarding its organoleptic characteristics, relatively to a commercial strain, used in industrial production, were carried out. In order to get the necessary data, sensory evaluations were carried out, using groups of untrained tasters. Also, in order to obtain the necessary amounts of the two non-commercial yeast strains that were used, lab growth was performed, using starter cultures. The results of the sensory evaluations are inconclusive, which indicates that the non-commercial strains can’t be considered to be better than the commercial strain, for this purpose. Specifically, it was considered that the differences between samples, namely, in the two evaluations that were carried out, weren’t significant, which makes the commercial strain (having a normalized production, low price, regularized regarding legislation) to still be the most favourable one. Regarding the final product, favourable nutritional allegations were achieved, which was part of the initial goal, according to the ruling legislation, such as: “High fibre content”, “Low saturated fat content”, “Low fat content” and “Protein source”. It was not possible to draw any conclusion regarding minerals, neither about their content, nor about their related nutritional allegations. These allegations can only be applied if the product is analysed and validated by a certified entity.

Annotation:

The mendicant friars, especially the Dominicans and the Franciscans, made an enormous impact in thirteenth-century Spain influencing almost every aspect of society. In a revolutionary break from the Church’s past, these religious orders were deeply involved in earthly matters while preaching the Gospel to the laity and producing many of the greatest scholars of the time. Furthermore, the friars reshaped the hierarchy of the Church, often taking up significant positions in the episcopate. They were prominent in the establishment of the Inquisition in Aragon and at the same time they played a major part in interfaith relations between Jews, Muslims and Christians. In addition, they were key contributors in the transformation of urban life, becoming an essential part of the fabric of late medieval cities, while influencing policies of monarchs such as James I of Aragon and Ferdinand III of Castile. Their missions in the towns and their educational role, as well as their robust associations with the papacy and the crown, often raised criticism and lead to internal tensions and conflict with other clergymen and secular society. They were to be both widely admired and the subjects of biting literary satire. As this collection demonstrates, the story of medieval Spain cannot possibly be fully told without mention of the critical role of the friars.

This book draws on Plato’s philosophy to throw light on contemporary leadership theory and practice. It combines an account of his thought with applications to modern case studies and approaches, in both politics and business. Rather than attempting to give a single ‘one-size-fits-all’ definition of leadership, his strategy was to break it into its different strands. He presents several ‘models’ of leadership, most of them images or analogies: the leader as doctor, navigator, artist, teacher, shepherd, weaver, or sower. Each model points to features of leadership that we intuitively recognize to be important (e.g. curing a social malaise, charting a new course, or weaving together the social fabric). Some were already in wide circulation in Plato’s time, like the shepherd and the navigator. What he did was to make them much richer and more complex. The book goes through the models individually, setting out the essentials of Plato’s thought and then illustrating each model with modern case studies—eighteen in total, including presidents, CEOs, and Nobel laureates. There is also a chapter comparing Plato’s models with four recent leadership approaches. Highly innovative in its approach, this book presupposes no prior knowledge of Plato, although those familiar with his philosophy will find it a fruitful way of re-reading his work. But the focus is first and foremost on leadership, rather than celebrating Plato’s achievements: the priority is to present a multi-faceted approach, which does justice to the complex phenomenon of leadership.

Annotation:

The urban condition is today being radically transformed. Urban restructuring is accelerating, new urban spaces are being consolidated, and new forms of urbanization are crystallizing. How can these transformations be deciphered? In this book, critical urban theorist Neil Brenner argues that confronting this challenge requires not only intensive research on urban restructuring but new theories of urbanization. To this end, Brenner proposes an approach that breaks with inherited conceptions of the urban as a bounded settlement unit—the city or the metropolis—and explores the multiscalar constitution, political mediation, and ongoing rescaling of the capitalist urban fabric, from the local and the regional to the national and the planetary. New Urban Spaces offers a paradigmatic account of how rescaling processes are transforming inherited formations of urban life, the role of multiscalar state spatial strategies in animating them, and their variegated consequences for emergent patterns and pathways of urbanization. The book also advances an understanding of critical urban theory as radically revisable: key urban concepts, methods, and cartographies must be continually reinvented in relation to the relentlessly mutating worlds of urbanization they aspire to illuminate.

Chapter 6 begins by introducing the reader to the Peloponnesian War and Thucydides’ history of it. An account is given of Thucydides’ explanation of his methodology and goal with his work. This is compared and contrasted to that of his predecessor Herodotus. Pericles’ Funeral Oration is discussed as a statement of the Athenian self-image in the context of war and empire. An account is given of Thucydides’ vivid description of the plague in Athens and how this eroded the political support for Pericles and thus ultimately led to the defeat of the city. Thucydides’ account of the Athenians’ negotiations with the Melians is given careful attention in relation to the issue of the use of power and international relations. While the Athenians effectively make a case for might-makes-right, the Melians appeal to a higher principle of justice. This sets the stage for a broader discussion of the nature of ethics. Careful attention is paid to Thucydides’ psychological and sociological observations about what happens when the fabric of society begins to break down in crisis situations.

This chapter investigates how Sartre instigates the first few moves of ‘pure’ immanence. Through following the progression of Sartre’s thought, there is shown a deepening engagement with immanence, which ultimately sets the foundation upon which the later thinkers build. In his early period, Sartre reworks Husserlian intentionality to bring about a repudiation of the transcendental ego. Following from this, in Being and Nothingness and the Critique, he develops a dialectic in which consciousness, while relating to an ‘outside’, is construed as also thoroughly embedded in that outside through the subject-body of the flesh and relations of desire. From this comes a conceptualisation of the In-itself and For-itself as simulacra or topological variations of a more primordial intertwining or fabric of univocal Being. In this sense, we are immediately taken away from the subject of social contract theory, insofar as this presumes an asocial self, and the notion of identity as the sine qua non of politics, insofar as this presumes the terrain of an inexplicable transcendent Other. This brings with it a new take on politics as an ethical practice – one that will be taken up and extended by the other three thinkers – in which we do not look for a transcendent outside or fracture/break in immanence through which to ground resistance, but rather work through and experiment with our situation or condition.

This chapter takes a look at how the life story sometimes takes the form of a renegotiation, a reassessment — and not always an entirely coherent one — of a Victorian childhood through twentieth-century eyes, rather than a straightforward narration of earlier life events. For those born in the late Victorian or Edwardian eras, their life story might be created in the 1960s, 1970s, or even the 1980s — a period of rising affluence and rapidly changing family values. Although Victorian families were not necessarily demonstrative and affectionate in ways that are recognisable to modern readers, these relationships mattered. Writers may not have consistently reflected upon how they felt about their parents, but many nonetheless wrote enough about their experiences of family life for us to attempt to explore the emotional fabric of family life. Of familial relationships, it was those between parents and children that the autobiographers returned to most regularly, and of these, relationships with fathers are in many ways the most straightforward to comprehend.

This chapter discusses the material frame of Tahrir Square. As a space, it has been shaped by the political-economic policies of the past four decades, which essentially turned it into an antihuman space, nominally suitable only as a “nonplace” that people passed through. A liberalized economy under the umbrella of a state that systematically redistributed income upward shaped demands for “bread, freedom, and social justice” as surely as it walled off Bulaq from communication with its urban surroundings, segregated Garden City to protect the imperial agents of the “Washington consensus,” and prepared downtown for private redevelopment. The causes of the revolution were inscribed in the urban fabric of its primary theater. It should be emphasized that the revolution-era character of Tahrir Square is incomprehensible without linking it to the growth of the formal parts of the expanding city, specifically the suburbs and their gated communities. But it is equally incomprehensible without similarly linking it to the even more significant growth of the informal parts of the city, and indeed the more general character of informality in many spheres of life, most significantly labor, which was systematically made precarious by the same design that poured resources into the new cities and slated Bulaq for extinction. However, the quotidian antihuman Tahrir Square depicted in the chapter has greater depth as a performance space than one might think.

As cities grow, the urban system expands and the contribution of each architect or urban designer into the system is different. Every increment is unique in its own character and expresses the attitude of the designer through it. Hence any increment into the system should be a continuation of what was existing before and should give due values to the existing condition without which the system tends to break. Doing so can lead to formation of a spatially sustainable fabric or city but to attain this kind of sustainability, every type of fabrics in every cities should follow a set of codes which are unique to themselves because spatial sustainability depends upon the spatial and social organization of spaces, geometric and configurational ordering of the space, culture and way of life in a city. Space syntax and spatial cognition were the methods used to identify parameters that contribute to spatial sustainability.

Coated woven fabrics are often used as stressed membranes in inflatable and tension structures. When the stressed fabrics in such structures are damaged locally, the damage site often provides a starting point for the propagation of a tear. In this paper, a micromechanical model is developed for predicting the onset of tearing at slit-like damage sites in biaxially stressed coated woven fabrics. The stress concentration in the first intact yarn adjacent to the slit is determined as a function of increasing remote stress, and predictions for tearing onset are made assuming that tearing initiates through the rupture of the first intact yarn when the maximum tension in the yarn reaches the yarn ultimate breaking load. A crucial aspect of the model is the treatment of inelastic deformation involving yielding and/or separation of the coating and relative slip between interlaced yarns near the slit tip. Inelastic deformation near the slit tip leads to significant reduction in the stress concentration compared with the elastic deformation case and, therefore, acts to inhibit the onset of tearing. A single dimensionless parameter is shown to govern the stress concentration at tearing versus slit length behavior of particular fabrics. The parameter may be interpreted as a measure of the slit damage tolerance of coated fabrics and shows how particular microstructural properties of the fabric (coating yield stress, coating shear stiffness, yarn axial stiffness, etc.) affect tearing onset. A series of experiments on various coated nylon and polyester fabrics are conducted using slit-damaged cruciform specimens in a simple biaxial test frame. Initial slit lengths in these tests ranged from five to 61 consecutive yarn breaks. The model is shown to capture the onset of tearing in these fabrics over a range of slit lengths quite well.

This project is of interest to those involved in construction, siting and repair of pipeline crossings of rivers, streams and estuaries. In early 1999, Mainline Pipelines Limited discovered that their pipeline crossing of the River Wye had been exposed by river scour. Originally laid in 1972, the line provides petroleum products main supply from the port at Milford Haven to the Midlands, England, and operates at a high pressure. A break in or temporary shutdown of the pipeline would have had serious implications. Remedial protection options were needed rapidly, to ensure the integrity of the pipeline. A review of historical air photographs and maps, dating back to 1888, showed that the meandering channel of the River Wye has shifted to the north at an average rate of 0.65m per year. Thus, the remedial works would have to account for ongoing vertical and lateral scour. It was recognized that river training works would be required at the site to ensure continued protection of the pipeline in the long-term. The recommended design and remedial construction techniques allowed for safety issues, the potential impact on the river ecology, recreational river users, the river hydrology and restricted access to the steep northern riverbank. The design comprised filling of the eroded riverbed and bank with rock aggregate and placing a protective layer of graded rock riprap. Grout filled fabric formwork bags were placed beneath the pipeline to minimise deflection and the development of unacceptable stresses in the exposed length during rock placement. Rock filled wire mattresses were placed immediately on top of the pipeline to protect it from point loading of the angular riprap. A satellite guided positioning system was used to control material placement, and environmental monitoring of river water quality was carried out continuously during construction.

In aero engines, the rotating shafts are supported by a set of bearings, which are enclosed in bearing chambers. Cooling and lubrication oil escapes from the bearings and these chambers are designed to capture and recycle it. A good understanding of the oil behaviour inside bearing chambers is therefore desirable in order to limit the oil volume involved and minimize transmission losses whilst managing the engine core heat in the best possible manner. This study is focused on the simulation of the oil behaviour inside such a chamber and special attention is given to the so-called KIT bearing chamber. The oil phase in the chamber can take different forms e.g. sprays, droplets, thin films or a combination of those. Assuming the oil we want to track remains dominantly as a film and large droplets/filaments, the Volume of Fluid (VOF) method is used in order to track the oil and the oil/air interface in the chamber, hereby investigating the feasibility and merits of such an approach and extending the earlier work carried out by the authors and colleagues. An Enhanced VOF approach coupled with level-set is used here unless stated otherwise. The simulated pump outlet condition, proposed by the University of Nottingham, is also employed in this study, to replicate an engine displacement pump. Since the use of VOF requires a refined mesh in the oil region, an adaptive mesh approach based on the volume of fluid gradient is developed and validated to control the total cell count for some of the cases reported here and limit simulation costs. The Adaptive Mesh Approach (AMA) can allow a better resolution of critical interfaces, better compute the oil break-up (within the limitation of the physical models used) and then track the droplets and filaments. Therefore, not only the CPU time cost might be reduced compared to a fixed mesh approach but significant physical aspects of the problem should be better accounted for. In order to inform the set up and parameters used with this method, and appraise its value for the proposed application, the experimental study of Fabre is used before the approach is applied to the KIT chamber. Good insight is obtained in terms of run time acceleration for such problem when combining the proposed VOF setup with adaptive meshing. Key set up parameters are quantified. The simulations carried out with the proposed set up are proving to be fairly robust and stable. Qualitative (physical) evidence is also encouraging and confirms the value of such an approach to the study of aeroengine bearing chambers.
