AbstractThis paper reports on a research program of modeling single and multi-phase granular flow. Both incompressible and compressible single-phase granular flow, as well as two-phase liquid/granular flow in a pressure vessel were considered. For the latter case, detailed results based on a viscous/Mohr-Coulomb closure were compared to existing formulations. Idealized test cases indicated that the numerical procedure is sound. Subsequent simulations of two-phase flow using realistic geometries and boundary conditions showed that the pressure distribution in the solid phase is fundamentally different for the Mohr=Coulomb system than for the conventional system. The effect of the angle of internal friction, geometry, and other parameters is discussed.
