概要

• 論文の詳細を見る

• We apply kinetic theory for moderately dense flows of identical, dissipative, frictional spheres to an inclined flow between vertical, frictional side walls over a rigid, bumpy, inclined base. We choose the coefficients of restitution for inter-particle and wall collisions to reproduce the measured height of the flow at the measured volume flow rate in the physical experiments. The resulting profiles of volume fraction and mean velocity are in good agreement with those measured on the centerline in the discrete-element numerical simulations. The profile of granular temperature has the correct shape, but the temperature is much higher than the measured values at the bottom of the flow and lower at the top.
