Comparison of Jet Pump Numerical Calculation Results in ANSYS and Openfoam CFD Packages

Abstract

Currently, among the most popular computational fluid dynamics software packages are commercial CFD packages – ANSYS CFX, ANSYS Fluent, STAR-CCM+ and several others. In contrast to the above-mentioned commercial CFD packages, there is an OpenFOAM, a non-commercial, freely distributed, integrated platform for numerical modeling of solid-state mechanics tasks (including CFD tasks), and it is becoming more and more popular. In addition to being a non-commercial package, OpenFOAM also has open-source code, which allows users to write their own algorithms for solving highly specialized tasks. A comparison of ANSYS and OpenFOAM in the application to CFD problems of incompressible turbulent flow in this article is given by the example of jet pump calculation, which was tested in the Laboratory of Hydraulic Machinery of Peter the Great St.Petersburg Polytechnic University.
