【Abstract】 Fixing attention on the active controlling causes of water hammer, for the long_distance water supply system, the optimal control of transient multiple valves regulation is put forward. In the condition of two valves regulating, one is located at outlet of the pump, and the other is located at the middle position of the pipeline; the transient multiple valves regulation for fluid transient is numerically simulated. The results show that the method is feasible.更多还原
