谏壁泵站进水流道的数模分析

Numerical Simulation of Inlet Duct of Jianbi Pumping Station

谏壁泵站进行增容改造后,进水流道是否能满足工程运行要求? 针对这个问题,应用时均N-S方程和k -ε湍流模型方程对谏壁泵站进水流道的流动进行了计算分析,并以流速分布均匀度和速度加权平均角度为优化目标对不同的流道方案进行了评估。结果表明,谏壁泵站原有的进水流道完全满足增容改造以后的要求。

The time uniform N-S equation and the k-εturbulence model are used to simulate the flow field of the inlet duct of Jianbi Pumping Station in order to solve the problem that whether or not the inlet duct can meet the requirement of pumping station operation after the pumping station is enlarged. The different scenarios of the inlet duct are evaluated with the optimization objectives of the uniformity of the velocity and the weighted mean velocity. The results show that the original inlet duct can satisfy the requirement of operation after the pumping station is enlarged.
