Morphotropic phase boundary in the BNT–BT–BKT system

Jean-François Trelcat, Christian Courtois, Mohamed Rguiti, Anne Leriche, Paul-Henri Duvigneaud, Tiriana Segato

Lead-free x Bi0.5Na0.5TiO3–y BaTiO3–z Bi0.5K0.5TiO3 piezoelectric ceramics were synthesized by a conventional solid state reaction method. The microstructure, ferroelectric and piezoelectric properties of the ceramics were investigated. Structure measurements by X-ray diffraction with Rietveld...

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...

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...

Study of the regenerator constituting material influence on a gamma type Stirling engine

Ramla Gheith, Fethi Aloui, Sassi Ben Nasrallah

A gamma Stirling engine with compressed air as working fluid was investigated. This engine operates at a maximum charge pressure of 10 bar, runs at a maximum rotation speed of 600 rpm and can provide 500 W of brake power on the shaft. The engine is equipped with several pressure sensors and...

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...
