采用数值计算的方法研究进水池的水力优化设计,可以排除由于试验条件、试验方法等不同而产生的影响,从理论上对其进行比较系统的研究。应用直接求解三维雷诺平均N-S方程和标准K-。紊流模型方程组的方法,计算进水池内的流场;根据轮流泵转轮的设计条件,引入流速均匀度和水流入泵平均角度两个目标函数,从而为开敞式进水池及水泵喇叭管的水力优化计算准备必要的条件。
The numerical calculation method is used to study the hydraulic optimization design of the intake basin. It can exclude the influence caused by different test conditions, test methods and so on, and make a comparatively systematic study in theory. Applications Solve the three-dimensional Renault average N-S equation and standard K-. Turbulence model equations method to calculate the flow field into the pool; According to the design conditions of the rotor pump wheel, the introduction of flow velocity uniformity and the average angle of water into the pump two objective function, which for the open inlet and pump horn The hydraulic optimization of the pipe is prepared for the necessary conditions.
