Bakun水电站叠梁高程对下泄水流溶解氧影响数值模拟

在库温分层条件下，Bakun水电站通过设置导水叠梁来获得表面取水效果，本研究采用数值模拟手段，模拟不同叠梁高程和不同水位时坝前库区流场分布和坝前溶解氧沿水深分布，然后计算出下泄水体中溶解氧的变化过程。为叠梁高程的选取提供技术支持。

Numerical simulation of training log elevation influencing on DO distribution in discharged flow of Bakun hydropower station

Under the reservoir temperature stratification,the results of diverting water from reservoir surface layer by setting up the training logs are obtained on Bakun hydropower station.In this paper,the numerical simulation is adopted to simulate flow fields and the dissolved oxygen(DO) distribution along the water depth before the dam via different training log elevation with different water levels,then the varying process of dissolved oxygen in the discharge water is calculated for the techical support on the choice of training log elevation.
