Numerical investigation of the location of maximum erosive wear damage in elbow: Effect of slurry velocity, bend orientation and angle of elbow

► A numerical simulation based on CFD and discrete element method was conducted. ► The solid-liquid interaction in fluid transportation progress was studied. ► The puncture point Location moves to downstream when slurry velocity increases. ► The puncture point location is significantly influenced by the bend orientation. ► Later half of the U-shaped suffers more frequently but lighter friction.
