摘要
堤坝等水利水电工程截断河流,鱼道能克服其阻碍作用,使鱼类顺利上溯洄游。采用RNG k-ε湍流模型对竖缝与堰组合式鱼道进行数值模拟,对其池室内流速以及紊动能情况进行分析研究。结果表明:该类型鱼道池室内部水力特性稳定,具有竖缝式鱼道和堰式鱼道共同优点,适宜于不同鱼类游过,能较好地适应鱼类上溯。
The hydraulic structures such as dikes and dams cut off rivers, and the fish way enables the fish to overcome obstructions and swim upstream. The RNG κ-ε turbulent model is applied to simulate the combined fish way consisted of weir and vertical slot, and the velocity and turbulent kinetic energy in the pool are analyzed. The results showed that the hydraulic characteristics of the combined fish way consisted of weir and vertical slot is stable ; the new fish way synergizes the advantages of vertical slot fish way and weir type fish way, which can help different fishes pass through dams and is suitable for the fishes to swim upstream.
