Solving the hydrodynamical tasks using CFD programs

Abstract

The possibility of performing hydrodynamic calculations in hydraulic machines using CFD software packages was considered. The main steps of the process of setting and solving the tasks were determined. Numerical studies of the spatial flow of fluid in the flow parts of hydraulic machines were carried out on the example of the bulb-type turbine, the reversible hydraulic machine and the centrifugal submersible pump. The results of calculations, namely, the visualization of the flow in the form of velocity distribution and pressure distribution, are presented. The analysis of the convergence of the results of numerical research with experimental data on the basis of determining the hydraulic coefficient of efficiency of the considering machines was carried out.
