Abstract
Erosion is a large problem in many industries. CFD modelling is used to model the process in order to enable the engineer to design better equipment. This paper discusses a novel solution to reduce computational effort, using OpenFOAM to combine two exiting solvers. The two phases of the bulk flow are modelled partially in the Eulerian-Eulerian reference frame, and partially in the Eulerian-Lagrangian frame. The method aims to reduce computational time, but still keep the necessary particle impact data at the wall required for erosion modelling. This paper is a continuation of a previous paper which was concentrated on the development of the new hybrid solver. The new solver was applied to different geometries and test cases, and was validated against experimental data. A submerged jet impingement test with different shaped impingement samples was used to generate experimental data of the fluid phase. The results show a promising outlook for the new solver to be used for more efficient erosion prediction.
