Kinetic theory models for granular mixtures with unequal granular temperature: Hydrodynamic velocity

摘要: Kinetic theory for granular mixtures with a separate temperature each solid phase is considered. The particle phases are assumed to follow Maxwellian distribution zero-order approximation of the Boltzmann equation. A solution strategy solving integrals collisional closure relations presented. present analysis enables these without neglecting hydrodynamic velocities in function. However, limits validity relatively small and moderate velocity differences. Dependent on magnitude difference, can differ significantly from simplified models where such difference traditionally neglected.
