A numerical evaluation of erosion on a surface of a pipe with double elbows was carried out. 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. The erosion rate was estimated by a new erosion model. The main results as follows : (1) A clear roping structure was seen at the elbows. (2) Due to the roping structure, the large magnitude of the erosion at the elbows was occurred. The numerical magnitude of the erosion was in good agreement with experimental results.
