Numerical Simulation Study on Hydraulic Characteristics of Static and Dynamic Water Opening of Fast Plate Valve
Aiming at the rapid hydrostatic and hydrodynamic door opening process of flat valve,the standard k-ε model combined with dynamic grid technology is used to simulate the hydrodynamic and valve load characteristics under the interactive coupling of valve motion boundary and hydrodynamic flow field,and the results of the gate lifting force are compared and analyzed with the scaled model test,and the trend of the results is basically the same.There is a local pressure gradient distribution when the door is opened by still water,but it has little influence on the flow force in the downstream flow direction and the vertical flow direction.When the water is moving,the initial value of the water flow force in the direction of the water flow is larger,and then gradually decreases with time.
