CFD simulation of sand particle erosion under multiphase flow conditions

It was noticed that the passage of slugs was intermittent and only then the particles impacted the pipe elbow at high velocities. Moreover, it was observed that in H-H elbow, maximum erosion occurred at the top of the elbow's outer wall. Qualitative results such as phase distributions, particle concentration, particle velocity and erosion pattern were used to investigate the erosion mechanism under such multiphase flow conditions.
