Abstract: The steady uniform shear flow in a low concentration fluidized gas solid granular flow is studied on the basis of the kinetic theory of granular flow and a modified BGK model equation. Explicit expressions of the pressure tensor are obtained as a function of the restitution coefficient. The computation shows the different normal stresses distribution. The results agree well with the Jenkins Richman theories, although significant discrepancy appears for granular temperature distributions.
