HYPOTHÈSES SUR L'ORIGINE DES BRUITS DU COEUR ET DES ACCIDENTS DE DÉCOMPRESSIO...
Nous avons proposé, dans un travail antérieur, l'hypothèse d'un phénomène de cavitation à l'origine des bruits de Korotkoff. Encouragés par l'aphorisme de MacDonald... -
Numerical and experimental study of creep of Grade 91 steel at high temperature
Grade 91 steel is a suitable candidate for structural components of the secondary and the vapour of generation IV nuclear reactors. Their in-service lifetime will last... -
Liquid and liquid-gas flows at all speeds : Reference solutions and numerical...
This paper present some reference solutions to be used in order to validate and improve numerical schemes for multiphase flows. We address here exact one-dimensional... -

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... -
In situ characterization and numerical simulation of cavitation upon explosiv...
This thesis was focused on cavitation damage in rubbers submitted to gas decompression. Previous studies have shown cavities appearance in elastomers when a level of... -

Dynamics of cavitation bubbles in micro-confined water under tension. Applica...
Liquids can sustain traction forces, as solids do. In this case, they are at negative pressure (that is, under tension), in a metastable state. Nucleation of a bubble... -

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... -
Modeling and simulation of compressible turbulence in two-phase : application...
The computation of cavitating flows is a challenging issue due to the characteristics of these flows : phase transition, large density gradient, Mach number variation,... -
Responses of tree species to global change : biogeographic and ecophysiologic...
Tree distribution could be highly affected by climate change. Results of paleogeographic studies showed that tree distribution ranges have already shifted with past... -
Study of the cavitating instability on a grooved Venturi profile

On the cavitation modeling using compressible Navier-Stokes equations and a h...
Cavitation is a phase change phenomenon, wich occurs in low pressure areas in hydraulic systems. Its consequences are often harmful and undesired : it causes loss of... -
Physico-Chemical Modifications of Chromium-Depleted Layers during High Temper...
The present work is focused on the consequences of oxidation at 950°C on the nature of a chromium-depleted area in Ni-based alloys. Two classes of alloys were analysed... -
APPLICATION HYDRAULIQUE DE LA TECHNIQUE GRAPHIQUE DE BERGERON AUX ACCIDENTS V...
Un poète de l’entre deux guerres a décrit les circonstances de son accident vasculaire cérébral, nous évoquant « un coup de bélier hydraulique ». Pour Ahlqvist...
