ABSTRACT
The formation of the turbulent twirled stream essentially differs from the forward. Under the influence of a centrifugal force in the twirled stream, there are pressure gradient on radius, the return currents, the raised speeds at a wall, non-linearity of a profile of tangential stresses, etc. In turn, these phenomena make strong impact on regularity of motion of drops of a liquid in a deduster and character of a current in a boundary layer on a phase boundary gas-a liquid, i.e., define both separation efficiency, and a water resistance, and a criticality of work of dedusters [1-9].
