Etude physique et numérique de l'écoulement dans un dispositif d'injection de...
A Pelton turbine is characterized by a water jet which is impacting rotating buckets. The main goal of this study is to understand the phenomena which are impacting... -
Contact line models for thin films
In the present work, we describe the dynamics of a moving contact line for thin films flowing down an inclined plane. Our focus is the problem of triple point located... -
Numerical study of liquid jets break-up in supersonic flows
This work deals with numerical atomisation of liquid jets. In the first part, a bibliographical review concerning liquid jets break-up is done. Numerical approaches... -
Displacement of an object through a yield stress fluid : boundary layer, yiel...
The behavior (flow, adhesion,...) of a yield stress fluid along a solid surface is a recurrent problem in many industrial processes. The non-Newtonian character of... -
Quelques problèmes fortement non-linéaires de surface libre et leur résolutio...
This dissertation deals with some highly non-linear free surface flow problems. The first part is dedicated to the study of the bursting of a bubble at the free <br... -
Microscopic origin of the rheological and surface properties of embryonic cel...
This thesis focuses on the experimental study of physical properties and biomechanics of embryonic cell aggregates. The aim of this thesis was on one hand to better... -
Local modeling of water-steam two-phase flows in steam generators.
The present study is related to the need of modeling the two-phase flows occuring in a steam generator (liquid at inlet and vapour at outlet). The choice is made to...
