Previous studies of the flow created inside a cylindrical cavity ~radius R , height H) of fluid by a single rotating end wall have shown that over a range of cylinder aspect ratios 1.6&H/R&2.8, the first unsteady flows to bifurcate with increasing Reynolds number retain axisymmetry, and subsequent bifurcations break axisymmetry to give solutions with modulated rotating wave ~MRW! states. The un...

Predicting the dynamics of dense granular flow plays an important role in engineering and geophysical flow which involve the transport of granular materials such as for instance cereals, rocks or sand. In the past decade, most of the studies have focused on the flow of granular material on inclined surface due to the obvious applications in rock avalanches, landslides and pyroclastics flows [14...
