竖缝式鱼道内部流场受加墩影响的数值模拟研究 Numerical Simulation on Flow Field of Vertical Slot Fishway with Plancon

采用标准k-e湍流模型对竖缝式鱼道内部受加墩影响的流场进行二维数值模拟研究。研究的情况分为三种，即不加墩、加墩、改变墩位置，对这三种情况的流场进行数值模拟计算，并应用物理模型试验成果进行对比验证。结果表明：在竖缝式鱼道的主流路径处加墩，可以在一定程度上降低鱼池的流速。 This thesis is to make two dimensions numerical simulation on flow field of vertical slot fishway by standard k-e turbulence model. The study is divided into three kinds of condition, that is, without plancon, with plancon, changing plancon’s position. The numerical simulation of flow field in these three cases is carried out, and the results of physical model test are compared and verified. The results indicate: adding the plancon to the mainstream path of vertical slot fishway can slow down the velocity in pool of fishway to a certain degree.
