| Abstract: | Based on the characteristics of solid liquid flows such as their density, concentration, elastic modulus and resistance, the unsteady coarse grained solid liquid flow in hydraulic hoisting is simulated. And the wave propagation speed equation, the continuity and momentum equation of water hammer in coarse grained solid liquid flows are theoretically derived. The simulating results can be applied to solve the problems of the unsteady coarse grained solid liquid flow in hydraulic hoisting in ocean mining, coal excavation and silt elimination from watercourse. |
