Abstract

The study describes a theoretical model of flow pattern of a newtonian liquid in a flat-bottomed cylindrical vessel with radial baffles at wall agitated by a standard six-blade disc turbine impeller, under turbulent flow. The model, comprising the description of the field of main mean velocity components and of Stokes stream function in the system, is identified by experimental determination of velocity field by means of Pilot direction tubes and hot-film anemometer. The resulting analytical description of the flow pattern in the vessel corresponds well to that found experimentally. Knowing three parameters derived from the velocity profile of the stream streaking from the impeller, the description depends only on the system geometry.
