Optimization of the flow part of the pump for abrasive-containing liquids by hydrodynamic modeling methods

Abstract

Abstract Abstact. In this article the severe operating conditions of pumps for abrasive media, as well as the complexity of obtaining an analytical solution to the wear problem are described. Optimization criteria for such pumps are selected. A mathematical model for calculating a ground pump is presented. The STAR CCM+ software package modeled 15 models with different geometries and identified the main geometry parameters that affect the rate of erosion. A weight function was created that characterizes the success of model optimization based on the selected criteria. According to the accepted parameters, 20 models were modeled and the best geometric dimensions of the flow part were selected. The results are analyzed and conclusions are drawn.
