Dense, rapid flows of inelastic grains under gravity

Standard hydrodynamic descriptions cannot describe the rapid flow regime of inelastic grains in the dense limit. Pointing out inelastic losses and the inelastic collapse phenomenon, we propose a new approach relying on a nonlocal dissipation scheme. Our modeling succeeds in accounting qualitatively and quantitatively for the linear profile of velocity evidenced in experiments conducted with gravity-driven densely-packed flows.
