A new erosion model was proposed due to a theoretical approach. Using of the erosion model, a new evaluation technique to estimate the erosion magnitude on a pipe surface was developed. The flow field was estimated by the k-ε turbulent model. And, particle motions were estimated by Stokes equation and bouncing coefficient by Tabakoff et al. Further, a numerical simulation for a elementary experiment was carried out. The main results are as follows : (1) The erosion rate depends on the particle size strongly. The result is in good agreement with the experimental result. (2) The effect of particle size for the erosion rate depends on flow field and experimental apparatus.
