Description du sujet de thèse

Understanding and predicting the flow of media made up of particles such as sand, snow and powders remains a real challenge. Their handling in industry is based on a rich but totally empirical knowledge. Similarly, predicting geophysical events such as snow avalanches and landslides requires a better understanding of these materials.
A major advancement would be the development of continuous descriptions of these powder flows, similar to what we can do in fluid mechanics. Recent progress in developing consitutive laws for granular media suggests the possibility of such treatment. The Phd's project will involve experiments, numerical simulations and theoretical approach to investigate the flow of powders around obstacle, a configuration of interest n many applications and which provide a test for continuum modelling. This work will be carried out within the European ERC project "CohPa" at the IUSTI laboratory in Marseille.
