急流交汇区控导二维数值模拟

The control and guide two-dimensional numerical simulation of jet intersection area

利用紊流数学模型对某尾矿库急流交汇区的水力特性进行了二维数值计算，分析了不同导流楔体对水流控导的作用以及对流速和压强分布的影响，数值模拟结果表明，采用洞身宽度1／6—1／4．8的楔体可以有效的改善水流流态，降低水流对主洞的冲击，可以满足安全泄洪要求。

This paper used the turbulence mathematical mode to make two-dimensional numerical simulation to jet intersection area of a tailing pond, analyzed the influence of different guide wedge to the role of flow control and guide control and to flow velocity and pressure distribution, the numerical simulation results showed that, using the wedge with hole body width of 1/6 - 1/4.8 could effectively improve the flow pattern, re- duced the impact of flow to main tunnel, could meet the requirements of safety release flood waters.
