Multiscale Modelling of Morphological Evolution of Rough Surface during Superficial, Volume and Evaporation-Condensation Diffusions

M. Bigerelle, Jérôme Favergeon, T. Mathia, Alain Iost

Fractal functions are used to model a metallic interface. An analytical model described by three partial differential equations is built to model time evolution of the surface during heating including three different mechanisms of diffusion: superficial diffusion (SD), volume diffusion (VD) and…

Fractal Dimension of Grain Boundary during Heating Comparison between Images Analyses and Monte Carlo Simulation

M. Bigerelle, Jérôme Favergeon, Alain Iost

There are few articles that mention fractal dimension in grain growth mechanism. Some authors build a simplified analytic model showing that initial fractal dimension of grain boundary has an influence on interface modification velocity. Nevertheless they postulate the relation where L is the grain…

On the definition of an average strain tensor for two-dimensional granular material assemblies

Stéphane Bonelli, O. Millet, François Nicot, Jamila Rahmoun, G. de Saxcé

The description of deformation of granular assemblies is one of the basic ingredients, in view of developing constitutive relations following a micromechanical line. Ignoring the deformation of particles, the macroscopic strain of a granular specimen results from the relative motions of particles,…

Analyse des structures tourbillonnaires et des mécanismes de transfert thermique dans les échangeurs de chaleur multi-rangs de tubes ailetés, Heat transfer mechanims and vortical structures analysis in multirow finned tube heat exchanger

J.V. Simo Tala

Dans cette thèse, nous analysons l’écoulement et les transferts thermiques convectifs dans des modèles géométriques d’échangeurs de chaleur multi-rangs de tubes à ailettes planes continues. Dans un premier temps, les phénomènes Aérauliques qui s’y développent sont mis en évidence par des mesures…, In this thesis, we analyze the flow and convective heat transfer in multi-row plain fin and tube heat exchangers. The aeraulic phenomena that occur in these devices are first highlighted by means of PIV and LDA measurements. A local study of horseshoe vortices production, development, spatial…

Fluctuations de température en aval d'une jonction orthogonale d'écoulements turbulents de températures différentes, Experimental and numerical studies of wall temperature fluctuations downstream an orthogonal junction with turbulent flows at different temperatures

Sébastien Menanteau

La problématique associée à ce travail de thèse concerne la détermination des causes de fatigue thermique dans des conduites hydrauliques. Ce travail porte plus particulièrement sur l’étude d’une zone de mélange orthogonale dans laquelle débouchent deux écoulements à différentes températures et…, This research work originates from thermal stress issues in hydraulic pipes. It specifically focuses on determination of thermal load created by mixing flows in orthogonal pipe junctions. Such mixing zones are commonly used to cool or heat the main flow. For high Reynolds number values and high…

Virtual Platform for Embedded System Power Estimation

Santhosh Kumar Rethinagiri, Rabie Ben Atitallah, Jean-Luc Dekeyser

In this paper, we propose a virtual platform for power estimation of processor based embedded systems. Our platform consists of a combination of Functional Level Power Analysis (FLPA) for power modeling and fast system prototyping for transactional simulation. In this proposal, we aim at esti-…
