Abstract: Transverse surface waves were produced in a rectangular open channel in the region where the otherwise steady, uniform, flow passed through a cluster of vertical circular cylinders. The cylinders could represent either ...

Abstract: Numerical simulations show that two‐dimensional granular solids in an inclined chute can flow as a steady, uniform stream or as intermittent groups, or slugs. Slugs, or groupings of the flowing solids, were found to be ...

Abstract: Boundary conditions are formulated for planar, smooth, rapidly sheared granular flows. The formulation allows the slip at the wall to be large compared to the local mean particle fluctuation speed. In previous work by ...

Abstract: A formulation by Bagnold for the constitutive relations in dense, rapidly sheared granular flows is reexamined in light of more recent developments based on the kinetic theory of dense gases. Bagnold's formulation expressed ...
