Abstract
We consider a mechanism for sand-particle separation by wind. A computational experiment has been conducted to find the possible characteristics of the structure of the mutual location of particles. We consider some scenarios for particle separation from the surface: the direct separation of particles by wind (without primary rotation) and the rolling of particles over the surface and separation after rolling. The critical wind velocities calculated for these two scenarios have made it possible to describe the probable states of surface particles as a function of wind velocity at the surface.
