Abstract
The study deals with a phenomenological description of a flow leaving the blades of different types of turbine impellers, which are always placed in a cylindrical vessel with radial baffles under turbulent regime of liquid flow. The flow description is determined by three basic characteristics of the proposed model: i.e. the diameter of a cylindrical tangential jet a, the width parameter of a cylindrical tangential jet σ and the parameter of the intensity of momentum flux in the flow leaving the turbine A. All these parameters were calculated from the measured profiles of mean velocity for different types of turbines (standard, closed and with profiled blades) in systems of various dimensions. From the results follows that for geometrically similar agitated systems the model parameters have the same values; they vary with the type of turbine used and are independent on the relative size and position of the impeller in the system.
