Abstract
The article is devoted to the development of the disk pump driven by a hydraulic motor at Bauman Moscow State Technical University Department of Hydraulics. The relevance of the dynamic pumps of this type has been described, and the necessity to investigate the mechanism of disk impellers operation using the tools of numerical hydrodynamic modeling, has been shown. The article presents the mathematical model used in computer simulation of the flow and the description of the testing bench. A comparison of numerical and full-scale experiments to confirm the adequacy of the mathematical model is introduced. A research showing the influence of some basic parameters of disk impellers on their characteristics (head, efficiency) has been performed. The figures of the scalar physical quantities distribution in the flow part of the pump and graphs of the pressure and efficiency dependences on the studied parameters are presented for a visual illustration of the results.
