Water supply and wastewater disposal are among the industries with intensive use of pumping equipment, the share of electricity consumed by pumps is more than 50% of the total energy consumption. One of the reasons for the decrease in technical and economic indicators of submersible pumping units is the failure of pump motors due to overheating during their operation. In this regard, the substantiation and development of methods of research and calculation of fl uid fl ow parameters around the pump motor, is an urgent scientifi c and practical task. The aim of the work is to provide conditions of stable cooling of pump motors at which the temperature of electric motor windings will be within permissible limits. To achieve this goal, the task of developing a methodology for modelling the turbulent vortex fl uid fl ow along the electric motor of a submersible pump is solved.
