Hydraulic Characteristics and Flow Structure in A Double Vertical Slot Fishway
研究分析不同水池长宽比条件下双侧竖缝式鱼道的水池流场结构及其水力学指标,为双侧竖缝式鱼道布置参数的优化选择提供技术依据。基于单侧竖缝式鱼道体型参数的研究成果,选取导板长度与水池宽度之比为0.25、竖缝宽度与水池宽度之比为0.15、导向角度为45°作为研究的基本体型;鱼道来流边界设置为压力进口,上游水深设置为2 m,出流边界设置为压力出口,下游水深设置为2 m;模型顶部设置为压力进口,进口压强为1.01×105 Pa,边墙设置为固壁边界。采用三维数…查看全部>>
The double vertical slot fishway,one of the basic types of vertical slot fishways,provides for double si-ded migration and is appropriate for large numbers of migrating fish.However,research on double vertical slot fish-ways has rarely been reported in China.In this study,a three dimensional numerical simulation model was used to investigate the flow structure and hydraulic parameters of the double vertical slot fishway with various pool-aspect ra-tios (the …查看全部>>
