摘要
The experimental investigation of inception cavitation of liquid-solid two phase turbulent flow has been carried out in a two dimensional hydraulic tunnel. The experimental result shows that the cavitation existing in the sediment laden flow is different from that in the clear water. We also found that the inception cavitation of sediment laden flow only has a weak relation with the shape of the experimental model in which the cavitation originated, yet it has direct relation with the density of sediment concentration in the flow and the diameter of the sediment particles and the distribution of particle sizes. The results given in the paper could be used for engineering designing and hydraulic machine making.
