Abstract: Onedimensional wave propagation in granular flow has been investigated using a threedimensional discrete element model (DEM). Cohesionless, dry, smooth, elastic, hard spheres are randomly distributed in a cylinderpiston ...

Abstract: Flows in a corrugated channel are investigated by a highspeed camera and a particle image velocimetry (PIV) system. The bottom wall of the rectangular channel was corrugated with periodic grooves while the top wall and two ...
