In order to ensure safe and reliable operation of Sangequan inverted siphon,hydraulic performance of water-filling process is simulated by using computational fluid mechanics software FLUENT.The VOF method is used to analyze the two-phase distribution of water-air under two operating conditions of 10m3/s and 14m3/s water-filling discharge.The velocity and pressure distribution are computed with VOF method.The results show that at two operating conditions,it is necessary to adjust the downstream gate for ensuring the operation of inverted siphon under normal water level;furthermore,when water-filling discharge is 14m3/s,it should be guaranteed that the air can be completely discharged by exhaust valve.Thus,the water to be filled with a smaller flow rate(Q≤10m3/s)and the downstream gate to be controlled can ensure the safe operation of Sangequan inverted siphon.
