Topics

The main topics of the colloquium are listed below:

1) how to account for polydispersity in granular flow theories, with respect to transport and dissipation of momentum, energy, etc;

2) how to account for the evolution of the particle size in complex flows: population balances and their coupling to the flow and the rheology;

3) numerical methods (for solving kinetic theory and/or population balance equations, but also discrete element methods …);

4) experimental evidences of the coupling between particle breakage and granular flow, and related problems (prediction of the distance traveled by an avalanche, on Earth or on other planetary bodies; attrition of grains during mixing and transport, dynamics and size distribution in planetary rings ...).
