In this thesis we address the numerical approximation of the incompressible NavierStokes equations evolving in a moving domain with the spectral element method and...

In this thesis we deal with the simulation of fluid-structure interac- tion (FSI) problems in hemodynamics, with the emphasis in data assimilation and simulation in...

In dieser Doktorarbeit wird ein partiotionierter Ansatz zur Lösung nichlinearer stark gekoppelter Fluid-Struktur-Interaktionsprobleme behandelt. Dabei werden die...

Atherosclerosis is an inflammatory disease which starts when low density lipoproteins (LDL) enter the intima of blood vessel where they are oxidized (ox-LDL). The...

Le code NSI3FS permet d'étudier l'effet du vent sur des profils de ponts et l'apparition d'instabilités aéroélastiques. Ce rapport fait suite à une série de travaux de...

The aim of this thesis is the study of the hydrodynamic self-noise under a SONAR dome from 10 Hz to a few kHz. For this purpose, three particular studies has to be...

The rupture of carotid atheromatous plaques is the major cause of cerebrovascular thromboembolic events such as strokes and ischemic attacks. To prevent this issue,...

Ce travail a pour but d'étudier la variation des modes propres d'une section de l'aorte en fonction de la nature des couches et de la géométrie. On se place dans le...

This thesis is divided in two parts. The main tool of this work is time optimal control. We first consider the Pontryagin maximum principle for control system of...

This thesis is motivated by the modelling and the simulation of fluid-structure interaction phenomena in the vicinity of heart valves. On the one hand, the interaction...

The objective of this thesis is to study the ability of model reduction for investigations of flow-induced vibrations in heat exchangers tube bundle systems.These...

This work presents a full scale experimental study on the aero-elastic wind/sails/rig interaction in real navigation condition with the aim to give a reliable database...

We here investigate the modeling of fluid-structure interactions. The fluid is viscous and inscompressible and the structure is subject to an imposed deformation....

In this thesis we focus on the numerical analysis and the development of efficient partitioned algorithms for fluid-structure interaction (FSI) problems arising in...

In several industrial applications, the vibrating structures are in contact with a fluid (fluid around the hulls of a boats, reservoirs, heat exchangers in power...

It is well established that concrete durability strongly depends on the capillary porosity of the material. Hence, structural health monitoring of concrete structure...

The work summarized in this memoir stem from one of the following two topics: the modeling and numerical simulation of coupled systems (Chapters 1-3) and the...

This thesis contributes to the verification and the validation of the Baer-Nunziato (BN) model, to modelize water ham- mer phenomena in industrial piping systems. It...
