Anthropogenic carbon dioxide (CO2) emissions, major contributors to the greenhouse effect, are considered as the main cause of global warming. So, decrease of CO2...

This manuscript deals with numerical methods for linear and nonlinear complementarity problems,and, more specifically, with solving gas phase appearance and...

The transport of solid particles in saturated porous material, subject to fluid flow occurs in natural environment and specifically in civil engineering. These solids...

A general method to build a pore network model from a 3D image of a porous material ispresented in this work in order to compute its permeability. A skeleton of the...

This thesis deals with the modeling of heat transfer in porous media subjected to high temperature. An upscaling procedure yields a macroscopic model based on local...

This PhD-thesis work is intended for the elaboration of a methodology for risk analysis of accidentai hydrocarbon pollution. This methodology is based on the...

Communications au sein d'un ensemble de dispositifs dispersés dans un milieu polyphasique, utilisant une modulation de la pression de la phase fluide du milieu...

Cette étude porte sur la modélisation et la simulation numérique des mécanismes de transferts d'énergie depuis la colonne d'arc en direction du milieu poreux dans les...

The groundwater flow in aquifers contain evaporite rocks can cause problems such as geo-mechanical subsidence or collapse. In this work, we focus on the development of...

Negative charge excess at the surface of clay minerals coupled with their high specific surface area implies that clay-rich media have transport properties very...

This thesis presents a thermodynamic and kinetic model of interactions between a fluid and ideal solid solutions represented by several end-members.<br />The...

Two approaches to characterize porous media in terms of pore size distribution (PSD) are developed within our ECPS team. The aim of this study is to experimentally...

This work focuses on the behaviour of porous triphasic media, particularly on unsaturated soils subjected to hydromechanical loading. A coupled elastoplastic...

In the present work, we study analytically and numerically the influence of the thermal conductivity and the thickness of the walls of a horizontal rectangular cell on...
