PLANE STEADY SHEAR-FLOW OF A COHESIONLESS ANTIGRANULOCYTES MATERIAL DOWN AN INCLINED PLANE - A MODEL FOR FLOW AVALANCHES .2. NUMERICAL RESULTS

The granular flow model proposed by Jenkins and Savage and extended by us is used here to construct numerical solutions of steady chute flows thought to be typical of such flows. We briefly state the equations and boundary conditions and present numerical solutions when the following model parameters of the Jenkins and Savage model are varied: (a) the coefficient of restitution of the particles under binary collision, (b) the number of particles per layer, (c) the inclination angle of the chute, and (d) the basal and free surface boundary conditions. We demonstrate that the Jenkins and Savage model may yield physically questionable results, that those of its extension differ markedly from them and are physically more reasonable in certain cases, but yield equally questionable results in others.
