The structure of fishway is the major factor that fish migrates successfully. The impact of pier head structure and horizontal interval of baffles on the hydraulic characteristics of a vertical slot fishway pool were researched. Twelve different working conditions were composed of two factors, namely, the diversion angle of pier head and the relative position of baffles. The RNG κ-ε turbulence model was used to simulate the hydraulic characteristics of fishway. The results indicate that the influence of pier head structure on hydraulic characteristics is mainly reflected on velocity and turbulent energy, and the smaller the diversion Angle, the smaller the velocity and turbulent energy are. The distance between flow deflector and baffler plate changed the mainstream flow pattern and area size, and then affected the distribution of flow velocity. When the relative position of b0/L=0.15 or so, the flow pattern in the pool was reasonable, which met the basic requirements of fish migration.

鱼道结构是影响鱼类能否成功上溯的主要因素,考虑墩头导流角和导隔板相对位置两个因素,组成12个不同工况,采用RNG κ-ε紊流模型研究了墩头结构和导隔板水平间距对竖缝式鱼道池室内水力特性的影响。结果表明,墩头结构对水力特性的影响主要体现在流速与紊动能上,墩头导流角越小,流速与紊动能也越小;导隔板间距改变了主流流态与面积大小,进而影响流速分布,导隔板相对位置b0/L=0.15左右时,池室内水流流态较为合理,符合鱼类上溯的基本要求。

鱼道结构是影响鱼类能否成功上溯的主要因素,考虑墩头导流角和导隔板相对位置两个因素,组成12个不同工况,采用RNG κ-ε紊流模型研究了墩头结构和导隔板水平间距对竖缝式鱼道池室内水力特性的影响。结果表明,墩头结构对水力特性的影响主要体现在流速与紊动能上,墩头导流角越小,流速与紊动能也越小;导隔板间距改变了主流流态与面积大小,进而影响流速分布,导隔板相对位置b0/L=0.15左右时,池室内水流流态较为合理,符合鱼类上溯的基本要求。

The structure of fishway is the major factor that fish migrates successfully. The impact of pier head structure and horizontal interval of baffles on the hydraulic characteristics of a vertical slot fishway pool were researched. Twelve different working conditions were composed of two factors, namely, the diversion angle of pier head and the relative position of baffles. The RNG κ-ε turbulence model was used to simulate the hydraulic characteristics of fishway. The results indicate that the influence of pier head structure on hydraulic characteristics is mainly reflected on velocity and turbulent energy, and the smaller the diversion Angle, the smaller the velocity and turbulent energy are. The distance between flow deflector and baffler plate changed the mainstream flow pattern and area size, and then affected the distribution of flow velocity. When the relative position of b0/L=0.15 or so, the flow pattern in the pool was reasonable, which met the basic requirements of fish migration.
