Abstract
This paper presents a numerical procedure to predict sand erosion and the interaction between the flowfield and the eroded surface. To simulate this phenomenon, the turbulent flowfield, the particle trajectory and the amount removed from the eroded wall are calculated iteratively. In computations of the flowfield, incompressible Reynolds equations and a high-Reynolds-number type k-e turbulence model are adopted. Assuming that the particle suspension is dilute, the collision of particles and the influence of particle motions to the flowfield are ignored. The erosion model proposed by Neilson and Gilchrist is used to calculate the weight loss. To verify this method, a 90°curved channel and a channel with a bump are computed. The results show that the present procedure can reproduce the sand erosion process and the temporal change of the flowfield qualitatively.
