Abstract:

Les interactions fluide-structure sont d'un grand intérêt en ingénierie et pour des applications industrielles et médicales. Comprendre les interactions entre des particules aux formes complexes et des écoulements peut mener à de nouveaux projets pour l'administration ciblée de médicaments, pour des micro capteurs de débit et à une meilleure compréhension du comportement des micro-organismes. Dans cette thèse, nous étudions l'interaction fluide-structure de particules chirales de taille microscopique à bas nombres de Reynolds. Les particules sont rigides et confinées dans une géométrie 2D ou f

Abstract:

The dynamics of semi-flexible fibres in shear flow and the effect of flexibility on the swimming speed of helical flagella are investigated. High aspect ratio particles such as carbon and glass fibres are often added as fillers to processed polymers. Although these materials have high rigidity, the large aspect ratiomakes the fibres liable to bending during flow. Other high aspect ratio fibres that behave as semi-flexible fibres include carbon nano-tubes, paper fibres and semi-flexible polymers such as the muscle protein f-actin. Most theoretical studies assume that fibres are either rigid or

Abstract:

This dissertation addresses the 3D flow through forming fabrics. In the first part of this thesis, the single phase 3D flow through certain specific fabrics was modeled. In practice, the Reynolds number of the fabric flow, based on paper-side filament diameter, is around 100. Consequently, it is not too surprising that the permeability of the fabrics was found to vary approximately as Re ⁻⁰˙⁴, which is intermediate between the expected low Re (Re⁻¹) and high Re (Re⁰) limits. The resistance of a multilayer fabric was found to be nearly equal to the sum of the resistance of each layer considered

Abstract:

Due to their unique structure and flexible choice of materials, electrospun degradable and biocompatible polymer fibres are considered to be extremely suitable for biomedical applications such as tissue engineering and drug delivery, either on their own or integrated within composites. Conventional electrospun fibre composites are typically based on non-woven mats and therefore limited to simple-curved geometries (films, membranes, etc.). For aqueous composites such as hydrogels, the hydrophobicity of the materials sometimes prohibits fibres to be easily integrated or distributed in these comp

Abstract:

Soil reinforcement with discrete flexible fibres has always been an issue for further research. In Geotechnical engineering field, the research on sandy soil has considerably been more than the clayey one. The main reason for this lack can be expressed as the complexity of clayey material due to their cohesion and interaction between clay and reinforcement.The present research aims to show possibility of discrete fibre usage in clay. For this purpose, selection of material has been conducted with special care to make the project outcome applicable to industry projects. The fibre which was used

Les matériaux composites à base de fibre carbone suscitent un intérêt grandissant dans l'industrie en général et avionique en particulier.

Cela permet d'envisager la construction d'aéronefs d'une très grande solidité tout en réduisant significativement leur consommation en carburant. Cependant les composites carbone sont relativement fragiles sous des efforts en flexion ou compression. Leur durée de vie est peu connue et dépend fort

Abstract:

The use of fiber-reinforced polymer composites formed via injection molding is of increasing interest due to their superior mechanical properties as compared to those of the polymer matrix alone. These mechanical properties, however, are strongly dependent on the fiber length and orientation distributions within a molded part. As such, there is a need to understand and model the orientation evolution of chopped fibers in flow in order to accurately simulate the final fiber orientation distribution within injection molded parts. As a result of this, accurate and reliable experimental measuremen

In this thesis we explore thulium doped silica fibre based sources, focusing on laser and amplified spontaneous emission behaviours.

This new process offers a trade-off between circular and non-circular fibre geometries by maintaining advantages of both configurations. An implementation process on fibre drawing towers is detailed for future large scale production of highly circular active

Abstract:

Within this research, factors affecting the orientation of injection molded long fiber composites in an end-gated plaque were investigated. Matrix viscosity was found to have a small effect on fiber orientation. The impact matrix viscosity had on orientation was dependent on fiber loading. At lower fiber loadings, the higher viscosity material had a more asymmetric orientation profile throughout the samples and less of a shell-core-shell orientation. At higher fiber loadings, there were few differences in orientation due to matrix viscosity. Fiber concentration was found to have a larger influ

Abstract:

Le déplacement d'objets allongés dans un fluide se retrouve dans de nombreux domaines tels que la récupération du pétrole, la production du papier ou la nage de micro-organismes. Dans ce travail, nous étudions le comportement d'une fibre cylindrique longue dans un écoulement en géométrie confinée (fracture, canal microfluidique). Dans un premier temps, les forces de trainée exercées sur la fibre ont été déterminées expérimentalement et numériquement en fonction de son orientation et de sa position dans l'ouverture. Lorsque la fibre est parallèle à l'écoulement, elle le perturbe faiblement et u

Abstract:

Large amounts of money are being applied to the construction of the next generation of spallation sources for neutron scattering. Neutron powder diffraction instruments will be an important element of these facilities and the incorporation of detectors into these instruments with a high neutron capture efficiency is desirable. A new detector design named the Flexible Embedded Fiber Detector (FEFD) has been developed and tested for this thesis. This detector is based on wavelength shifting fibers embedded in a zinc-sulfide lithium-fluoride based scintillator. The virtue of this design is that t

Abstract:

Detta projekt undersöker olika alternativ av design utav transmissionskedja för ett vågkraftverk. Designen av koncepten kan delas in i två grupper, en grupp med styva länkar och rörliga leder och en annan grupp med stela leder och böjflexibla länkar. Analysen genomförs genom att undersöka olika tvärsnitt och olika material. De material som länkarna undersöks för är kolstål, rostfritt stål, aluminium, glas- och kolfiberkomposit. Analyserna utförs analytiskt för transmissioner med stela leder och böjflexibla länkar och för styva länkar med rörliga leder används Solidworks tillsammans med Ansys W

Abstract:

Os filtros de fibra flexível são módulos de filtração recentemente desenvolvidos cujo leito é constituído de fibras de poliamida, o que permite a obtenção de altas eficiências de remoção de sólidos associadas a altas taxas de filtração. Este estudo objetivou avaliar o desempenho deste tipo de filtro utilizando-se como meio filtrante fibras flexíveis de sisal e de polipropileno. Com isso se buscou aprofundar o entendimento da técnica de filtração em leito de fibras flexíveis, além de propor e avaliar leitos com fibras diferentes daquelas citadas na literatura (constituídas de poliamida), neste
