The article describes a theoretical model of two-dimensional flow of a homogeneous liquid in a cylindrical space delimited by the shell of the mixing tank with a conical bottom, radial baffles and a high-speed axial impeller rotating in a cylindrical draft-tube. By means of the analytical solution of vortex flow equation the mean time flow of turbulent liquid in the vertical cross section of the vessel may be described in the form of Stokes stream function or mean velocity components. The results of theoretical description of the flow are in a good agreement with the experimental values measured by a Pitot direction tube and a hot film anemometer.
