Abstract. The authors have set the boundary conditions for solving the finite difference equations of motion of the gas-dispersed flows in dynamic gas washer. The problem of boundary value modeling of swirling current of gas suspension in the conditions of changing spin flow, is solved. It is established that the change of the parameters of spin can cause the reverse current near the walls of gas washer. According to the results of calculations, the authors revealed the streamlines and velocity profiles at different cross sections of flow which made it possible to analyze and improve the design of the considered gas washer.

Key words: swirling zones, solid wall, condition of adhesion, velocity profiles, boundary conditions, current function.
