Rédigée en 2009 / Comparaison des résultats obtenus avec le Hole Erosion Test et Jet Erosion Test sur différents sols et classe de sol (USCS) / Expérimentations in-situ du Jet...

Wet granular materials are made of solid particles in high concentration, immersed in a viscous fluid. We investigated particle dynamics in a model granular suspension...

The earth's climatic system consists in several components which strongly interact (atmosphere, ice sheets, oceans, lithosphere and biosphere). Numerical modelling is...

Boiling phenomenon, from an energetic point of view, presents a real stake in many fields. This thesis presents an experimental study of a single vapour bubble created...

My research topics deal essentially with development and application of simulation tools for water, mass and heat flow in aquifer structures. I try and give some...

La détermination des effets d'hystérésis dans un sol non saturé exige des techniques expérimentales qui doivent permettre de déterminer d'une manière non destructive...

Among the microwave plasma torches, the axial injection torch (TIA) has been used for several years to create chemically active species, in applications such as gas...

Observations of crystal orientations on deep ice-cores from Antactica and Greenland have shown that polar ice acquires a fabric, characteristic of the strain-history...

The song of dunes is a natural phenomenon that have arisen men's curiosity for a long time, from Marco Polo to R.A. Bagnold. Scientific observations in the XXth...

The ice flows by plastic deformation under gravity, and by sliding over the bedrock, when local temperature is close to the melting point. Mechanical test in...

The hydrodynamic behaviour of the fixed film wastewater treatment processes is a significant factor affecting performance. This behaviour can be studied with the help...

In heterogeneous media, flow and transport usually take place in preferential flow channels. Thus, it is of prime interest to take the associated physical processes...
