鱼道出口段闸门不同开启高度下水力特性研究OA

During the operation of the fish way,the opening height of the gate will have a significant impact on the hy-draulic characteristics of the fish way,thereby affecting the fish passage effect.A numerical model was established based on the actual dimensions of the prototype fish way outlet section of Laokou Hydraulic Complex.Numerical simulation calculations were conducted to analyze the hydraulic characteristics of the fish way outlet section under different gate opening heights,such as water levels,flow patterns and turbulence energy etc.The results demon-strate that when the gate opening is 20%,the water level along the fish way is the lowest;when the gate opening is 80%,the water level along the fish way is the highest;the water levels along the fish way are similar under the rest gate openings;the optimal gate opening range is 60%～80%.
