CFD simulations have been carried out by combining DPM to predict the erosion rate and particle impaction regions in carbon steel 90° elbow with a diameter of 50.8 mm.
The current research on CFD simulation of erosive wear in literature was performed with discrete element modeling or discrete phase modeling to simulate wear due to erodent impaction [12].
