针对竖缝式鱼道水力特性较复杂的特点,采用雷诺应力方程模型对同侧竖缝式鱼道池内的水流进行了二维数值模拟,并将数值模拟结果与物理模型试验结果进行了对比,验证了数值模型的正确性。进而建立了水池长宽比分别为5∶8、10∶8、12∶8三种鱼道模型,分别对底坡为1%、3%、5%三种条件下的鱼道水力特性进行了数值计算,得到了水流型态和竖缝最大流速、流速场、紊动能、雷诺应力等水流物理参数的分布规律。
Aiming at the complex hydraulic characteristics of vertical slits, the Reynolds stress equation model was used to conduct two-dimensional numerical simulation of the water flow in the slits of the same-side vertical slits, and the numerical simulation results were compared with the physical model tests. The correctness of the numerical model is verified. Further, three fish-pond models with 5: 8, 10: 8 and 12: 8 pool aspect ratios were established respectively. The hydraulic characteristics of the fish tracks under three conditions of 1%, 3% and 5% The distribution law of the flow pattern, the maximum flow velocity, the velocity field, the turbulent energy and the Reynolds stress of water flow were obtained.
