Numerical and Experimental Investigation of Erosion on Surface

One of the major concerns in the field of valves operating under severe conditions such as high temperature is their interaction with other surfaces. These valves are used to pass gas. These gasses are sometimes corrosive and can cause wear of the surface which in turn affect the geometry such as roughness etc. For precise utilities, even small change in the geometry highly affects its performance as well as their precision. Therefore, the ability to predict the wear in these valves is highly valuable. In this paper, a numerical model based on the solution of flow and concentration equations is developed to predict the wear in the surfaces which are adjacent to hot gases. The output of this model is used as input to another model to predict the wear. The predictions of this model are verified by comparing to other numerical models as well as experimental data. The predicted values are in accordance with experimental data with acceptable accuracy.
