| 中文摘要: |
| 对竖缝式鱼道的水流结构进行了数值模拟计算，系统研究了鱼道水池长宽比和隔板墩头布置体型对水池内水流流态的影响。研究表明，鱼道水池长宽比是影响竖缝式鱼道水流结构的主要控制因素，长宽比在8∶8～10.5∶8的范围内，可以获得较好的流态。研究还表明，隔板是否设置墩头对水流结构的影响有限，从避免漂浮物滞留与防止泥沙淤积角度看，在实际的鱼道工程中可考虑不设隔板墩头。 |
| 英文摘要: |
| By means of numerical simulation and physical verification, the flow structure in a vertical slot fishway was studied, especially for the effects of geometrical parameters, including the length/width ratio of the pool and introduction of central baffle of different lengths. The results indicate that the length/width ratio has a significant impact on flow pattern and central baffle only has minor effect in changing flow pattern. In order to obtain favorable flow patterns in practice, an appropriate length/width ratio 10∶8 and the design without central baffle are recommended. |
