Metal erosion due to particles at high velocity and temperature

Abstract

Study of erosion is of great of importance because of its impact on the overall metal degradation. The main purpose is to minimize erosion because in most systems it is one of the biggest reasons of failure. Different models have been studied recently; however they are all at subsonic speed with standard environmental conditions. Erosion can be seen at the places where the interaction is for smaller time such that corrosion can't take place and all the loss of mass is due to the impact. In this study the numerical simulation was conducted to calculate the erosion rate at high supersonic speed. The problem is specifically related to the erosion at the speed range of 2000 - 3000 m/s and temperature as high as 3000K. An analytical model is also implemented to compare and validate numerical results as well as to propose a better analytical model for high speed.
