It is shown that erosion is primarily numerically studied using two approaches: computational fluid dynamics passed techniques and finite-element modeling based techniques. The review has also revealed that, depending on the application, CFD-based methodologies successfully utilize popular eddy viscosity models such as k-omega shear stress transport, standard k-epsilon models etc., and reynolds-stress models. However, the choice of semi-empirical or analytic erosion models applicable for CFD-based methodologies is still ambiguous and subject to specific application. FEM-based methodologies due to usage of an explicit dynamics solver allow for successful estimation of fundamental wear processes of the surface for various materials and can serve as a framework for further deep research and developm...
