摘要
随着社会越来越重视生态环境,在修建大坝时,为了鱼类的洄游不受影响,鱼道的修建显得格外重要。为研究单侧竖缝式鱼道的水力特性,以便于优化鱼道设计,笔者采用ANSYS软件对单侧竖缝式鱼道进行数值模拟,分析水池长宽比、导向角对鱼道水力特性的影响。研究结果表明,水池长宽比取10∶8、导向角取45°时,速度、压力与湍动强度大小适中且分布均匀,水流流态最优。
With the society paying more and more attention to the ecological environment,the construction of fishway is particularly important in order to protect the migration of fish during the construction of dam.In order to study the hydraulic characteristics of single side vertical slot fishway and optimize the fishway design,this paper numerically simulates the single side vertical slot fishway through ANSYS,and analyzes the effects of pool length-width ratio and guide angle on the hydraulic characteristics of fishway.The results show that when the length-width ratio of the pool is 10:8 and the guide angle is 45°,the velocity,pressure and turbulence intensity are moderate and evenly distributed,and the flow pattern is the best.
