Abstract
The sedimentation of grains in a fluid layer convecting as a system of rolls is studied experimentally and numerically. Large grains (diamet er 8 to 10 mum) accumulate along single lines at the bottom of the ris ing separatrices of the rolls. Small grains (2 mum) form double banks. This is correctly predicted by the numerical simulation.
