反调节水库非恒定流数值模拟

Numerical Simulation of Anti-Regulating Reservoir

采用二维水深平均方程组作为控制方程 ,利用边界拟合法进行坐标变换 ,采用有限体积法计算反调节水库的流场。在计算中 ,由于已知上游泵站抽水流量及下游枢纽供水流量 ,且上下游均找不到水位流量关系 ,上下游边界均为流速边界条件 ,没有压力边界条件 ,解不惟一 ,所以采用全水库水量平衡方程作为补充方程来补充定解条件。

In this paper the flow field of anti-regulating reservoir is computed and the feasibility of construction pumping station is analyzed. The body fitted coordinate method and the finite volume method are adopted to compute the flow field of anti-regulating reservoir. In both upstream and downstream, the flow velocities are adopted as boundary conditions, and a supplementary equation is adopted in order to maintain only one solution.
