Vitesse de chute d'une particule lourde isolée dans un écoulement turbulent
The settling velocity of isolated spherical particles, in grid generated turbulence, points out the role of the vortex structures in sediment process. The analysis of mean and turbulent velocities fields shows that the ratios between turbulence scales and characteristics of the particles are of great importance on the settling velocity evolution.
