| Abstract: | According to the characteristics of silt-laden water flow and based on the momentum equation of solid-liquid two-phase flow, the flow feature and velocity distribution pattern of silt-laden water flow in the chamber between the shrouds of centrifugal impellers are qualitatively analyzed in theory. The relationship between erosion intensity and velocity as well as the factor affecting erosion are derived. |
