Abstract
Boundary conditions are developed for rapid granular flows in which the rheology is dominated by grain–grain collisions. These conditions are at the wall and to adopt the no-slip condition. Exceptions occur where d/h is not very small, when the wall is not rough, and when the grain–wall collisions are very elastic. Similar insight into other flows can be obtained qualitatively by a dimensional analysis treatment of the boundary conditions. Finally, the more difficult problem of self-bounding fluids is discussed qualitatively.This publication has 7 references indexed in Scilit:
