Abstract
Using the one-equation turbulence model of Part I, rapid flows of granular materials are studied. The equations governing the transport of mass, linear momentum and fluctuation energy are considered. For simple shear flows, the dependences of the stress—shear rate relationship on the coefficient of restitution and solid volume fraction are studied. Couette and gravity flows of granular materials in rapid flow regimes are analyzed. Velocity, solid volume fraction and fluctuation energy profiles are calculated. The results are compared with those of the other theoretical models and the existing experimental data. It is shown that the predictions of the turbulence model agree reasonably well with the experimental data.
