THE KINETIC MODEL FOR COLLISIONAL STRESSES IN RAPID GRANULAR FLOWS

  • Particle collisions are the main mechanism of the momentum transfer, the energy transfer and the energy dissipation for rapid granular flows. Therefore, attention is paid to the collisional stresses in the study of rapid granular flows. Based on an inelastic collisional model of uniform, smooth and spheric particles, the collisional stress tensor, the collisional energy flux and the rate of energy dissipation, which are expressed in integral forms, are all obtained in this paper by analogizing the method in...
