Aeolian transport with collisional suspension.
This paper considers the aeolian transport of sand by a wind so strong that the concentration of sand near the bed makes collisions between grains inevitable. It employs an improved model of such a collisional flow which includes turbulent suspension, viscous dissipation and new top boundary conditions that are validated by numerical calculations of collisionless trajectories.
