Abstract

The hydrodynamics of the flow in a mixer-equipped vessel is investigated, proceeding from common notions concerning eddy currents. Here, the basic difficulty of the scale conversion of results of laboratory investigations to industrial vessels and conditions consists in the fact that no mixer-equipped vessels have been modeled.

The overall physical pattern of flow, which is characteristic of eddy-type vessels is formulated. A relationship is derived for calculation of the circumferential velocity component νϕ along radius r with allowance for the intensity Rer of the radial flow.

The damping effect of Rer on the structure of the flow within the limits of the central static vortex is established. The character of the liquid flow in the near-wall zone is determined; this made it possible to expand the range of analysis and reduce the boundary conditions at the wall to νϕ = 0.
