Numerical simulation of the tube erosion resulted from particle impacts

In this paper, tube erosion caused by the turbulent flow of a dilute particle-laden gas is studied numerically. The particle impact and rebound model and the erosion model of ductile alloys obtained by Tabakoff et al. are used to predict the particle rebound phenomena and the erosion suffered by the tubes. The results obtained in this study include the distributions of particle collision frequency and erosion of tube surface.
