Abstract

Constitutive relationships are developed in this present study for inhoinogeneous dense rapid granular flows of identical smooth highly inelastic spheres. The important mean fields in this flow are the solid fraction, mean velocity, and full second moment of fluctuation velocity. By extending constitutive theories for homogeneous granular flows of highly inelastic spheres by Richman\ Chou", and Chou & Richman^, the constitutive relationships, which consist of collisional source of second moment, collisional flux of second moment, and collisional flux of momentum, are based upon an anisotropic Maxwellian velocity distribution function. To apply this constitutive theory
