摘　　要：集鱼槽的布置及体型直接影响着集诱鱼水流的水力学特性,是整个集诱鱼系统设计的关键。为分析集鱼槽的布置及体型对诱鱼水流的影响,采用RNGκ-ε紊流模型和VOF模型对某水电站集诱鱼系统不同参数进行三维数值模拟,并通过物理模型试验验证数值模拟结果的合理性。结果表明,集鱼槽适合布置在尾水隧洞下游,集鱼槽宽度对诱鱼水流影响较小,而导墙长度和集鱼槽布置角度是影响诱鱼流速的关键性因素,同时集鱼槽布置角度还会对诱鱼口的紊动能场产生一定影响。The layout and geometrical design of the fish collecting system directly affect the hydraulics characteristics of the trapping water,which is the key to the success of the whole system.In order to analyze the effect of layout and geometrical design of fish collecting system on the fish luring velocity,the RNGκ-εturbulence model and the VOF model were used to simulate a fish collecting system.Its Location,width,length of the guide wall and defletion angle were considered respeetively in the present work.The numerical simulation results were verified by physical experiments.The results show that the fish collecting tank is suitable to be arranged downstream of the tail-water tunnel.In comparison with a limited effect of the width,the length of the guide wall and the deflection angle are two major factors on velocity distribution of fish collecting system.Moreover,the arrangement angle of the fish collecting tank will have a certain effect on the turbulent kinetic energy field of the fish luring mouth.
