The paper studies the contemporary state of the numerical simulation of erosive wear by solid particles in gaseous flow based on representative publications in Russian and foreign journals. 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 development of new analytical models. Opposite, CFD-based techniques are suitable for engineering tasks, and receive general system parameters as boundary and initial conditions. Regardless of these propitious conditions, currently no studies are published concerning the development of an entire technique which would allow the use of CFD approach based on the erosion models, pre-developed for a range of surface materials, particle velocities, impingement angles, etc. Such methodology, hence, is proposed for development and validation in future studies.
