Alternative design of double-suction centrifugal pump to reduce the effects of silt erosion

Doi:https://doi.org/10.3390/en12010158

1.The silt size affects the erosion position and erosion strength, whereas the silt concentration mainly affects the erosion strength for the studied range.

2.The bionic convex domes provide an effective solution to improve the silt erosion for most of the investigated silt-laden conditions.

3.The bionic convex domes reduce silt erosion bychanging the relative velocity ofwater around the blade surface and decreasingthe mass flow rate of silt particlesthathit the blade by inducing swirling flows.
