Effect of Velocity Variation on the Rate of Erosion Wear at the Elbow of the Slurry Pipe by Using CFD

In this manuscript, the rate of erosion wear in a 90° bend pipe has been investigated with the help of computational fluid dynamics code FLUENT 15.0. Erosion of the surfaces is one of the biggest industrial problems where the solid particles are transported. This manuscript highlights the effect of flow velocity on the solid particle erosion rate on the fluid-carrying pipe. The size of the sand particles and their concentration is kept constant, i.e., 200 μm and 5%, respectively, which are injected from the inlet surface at flow velocity ranging from 2.5 to 20 m/s. The computational modeling proves its importance in demonstrating the erosion rate of the solid particles as well as its complex flow behavior.
