The equation of convective diffusion of particles is considered, and the problem is formulated on the separation of dust particles from a turbulent gas flow in a parallel flow cyclone. The equations of pulsation motion of particles in the field of the action of the centrifugal and Coriolis forces are analyzed, and an analytic dependence is obtained for their diffusion coefficient.
