Rational Technique for Multistage Centrifugal Pump CFD-Modeling

Abstract

This article reports CFD-modeling technique of flow through a kerosene pump and suggests appropriate CFD tools, model configuration, types of boundary conditions, turbulence models and meshing technique. The flow features were analyzed and error of the CFD-model was estimated. The CFD results were compared with experimental results. The final CFD-model, which was also verified with the impeller radial load estimation, shows that the technique produces sufficient accurate results with less computational cost. The technique can be used for the design optimization of a multistage pump.
