摘　　要：采用Realizable k-ε双方程紊流模型对侧式进／出水口水流运动进行数值模拟,研究了体型对进／出水口水头损失和孔口附近流态的影响,指出了扩散段水平扩散角和整流段长度对水头损失和孔口流态的决定作用．最后给出进流工况自由水面随库水位变化情况．计算结果和试验结果基本吻合．The flow in side inlet/outlet of a pumped storage plant is simulated numerically using the Realizable κ-ε turbulent model. The influence of different bodily forms of side inlet/outlet on the head loss and flow characteristics is investigated. The results show that the horizontal divergent angle of divergent segment and the length of regulation segment have a crucial effect on the head loss and flow characteristics at the orifice. The change of free surface with the reservoir level under the pumping condition is simulated. The simulated results are consistent with the experimental results.
