Power losses and lubrication in automotiv gearbox
Reducing fuel consumption and automobile emissions are nowadays the main topics of research for the automotive industry. Therefore, the situation involves... -
A multi-physic and multi-phase approach of the lubricated contact
Classically, many assumptions are used to model the fluid behaviour in a lubricated contact : continuous film, constant viscosity across the film thickness, film... -
Surface optimization and new cavitation model for lubricated flow
This work deals with the modeling and simulation of contact between piston rings and liner of an engine. In the engine, the piston-rings are in relative motion with... -
Drying of complex fluids near the contact line : experimental and numerical s...
We study the pattern formation induced by drying colloidal suspensions and polymer solutions in a vertical Hele-Shaw cell immersed in a reservoir (dip-coating like... -
Effets d'anisotropie par homogénéisation dans un problème à frontière libre
The Elrod-Adams model is a pressure-saturation formulation which takes into account cavitation phenomena in thin fluid films mechanics. We study the asymptotic... -
Effect of thin water film on tire/road friction
Water film on pavement surfaces entails a decrease of friction between the tire and the road. Nevertheless, only effects of water films above 1mm depth were... -
Theorical and experimental analysis of rotor dynamic on airfoil bearings
These last decades numerous model for airfoil bearings have been developed. But nowadays, these models are not sufficiently accurate for the rotor response prediction... -
Modélisation numérique multi-échelles des contacts lubrifiés
" Modélisation numérique multi-échelles des contacts lubrifiés - Aux frontières de la mécanique (des fluides, des solides), de la thermique et de la physique de la... -
Analysis of the Behaviour of Lubricated Mechanical Systems
La plupart des mécanismes sont lubrifiés par une huile, une graisse ou plus simplement de l'air. Dans tous ces mécanismes, des pièces sont en contact, frottent,...
