带横向自压管道的开敞式调节池体型优化

调节池与泵站进水池相似,具有调节流态的功能等,但传统泵站进水池的出水管多为竖向布置且靠外力吸水,而调节池出水管横向布置且依靠水流自身重力出流.为此,基于FLUENT平台,采用雷诺时均N-S方程、VOF模型及RNG κ-ε湍流模型,通过单因素控制法研究了调节池的几何参数变化(调节池长宽比、调节池宽度、出水口边壁形状)对调...

Optimization of the Shape of Horizontal Self-pressing Outflow Open-type Pressure Regulating Tank

The pressure tank is similar to the inlet tank of the pumping station,and has the function of regulating the flow pattern.However,the outlet pipe of the inlet tank of the traditional pumping station is mostly arranged vertically and sucks water by external force,while the outlet pipe of the pressure tank is arranged horizontally and flows out by the gravity of the water flow.For this reason,based on the FLUENT platform,Reynolds time-averaged N-S equation,VOF model,and RNGκ-εturbulence model and the single factor control method were used to study the impact of the geometric parameter changes of the pressure tank(the length-to-width ratio,the width,the wall shape of the outlet)on the hydraulic performance of the outlet section of the pressure tank.The results show that the hydraulic performance is the best when the length-to-width ratio of the pressure tank is 7,the width is 6m,and wall shape of the outlet is a rectangle with rounded corners.
