    Feb 01 2012 · A numerical simulation based on CFD and discrete element method was conducted. The solid-fluid multiphase flow problem in concrete pumping progress was studied. A model for understanding the erosion severity on the wall was established. The maximum erosion was observed at 30°40° of the outer wall. The results have good agreements with those observed in actual case.
