Dense flows

Educational objectives

The aim of this lab-course is to tackle the problem of the modeling of dense gravitational flows dynamics.

Dense avalanches of granular materials will be produced and analyzed with the help of a laboratory inclined plane equipped with advanced instrumentation: granular PIV, fringe projection, etc. The experimental granular avalanche-flows will then be reproduced by numerical simulations based on shallow-flow (Saint-Venant) equations.

The emphasis will be on comparing the propagation and the final stopping of laboratory and numerical avalanche-flows, with the objective of inferring the relevant rheological parameters of the studied granular fluid.
