Abstract

A new numerical procedure is proposed to analyse solid particle erosion caused by slurry. The procedure works involves two mechanisms. First, high-concentration particles are considered as a continuous granular phase and tracked through the Eulerian–Eulerian two-fluid method. Second, the continuous granular phase near the pipe wall is converted into discrete incident and rebound particles by a particle separation method. The procedure is validated through comparison with experimental data available in the literature. Additionally, the performance and efficiency of the new method are compared with those of the dense discrete phase method and the discrete element method.
