AbstractSand concentration and particle size are the main factors that affect the erosion of solid surfaces under the impact of solid particles in liquid-solid two-phase flow. In this study, five sand concentrations (1 wt%, 3 wt%, 5 wt%, 10 wt%, and 20 wt%) and five particle sizes (20 mu m, 75 mu m, 125 mu m, 300 mu m, and 425 mu m) were used for V-groove Surface mud erosion is simulated. Gambit and Ansys Fluent were used to simulate the anti-erosion performance of the V-shaped groove. The flow field near the V-shape grooved surface was analyzed for the explanation of the erosion behavior. Corresponding experiments were also carried out to verify the simulation. The results showed that the slurry erosion of the V-shape grooved surface increased with the increasing sand concentration. There was a critical particle size between 25 mu m and 75 mu m, above which the slurry erosion remained stable with the particle size. In addition, no great change occurred in the flow style for all cases with different sand concentrations and particle sizes. The erosion area did not change with the increasing sand concentration but enlarged with the increasing particle size. The erosion mechanism with different sand concentrations and particle sizes was also discussed.
