| 摘 要： | 基于Navier-Stokes方程和标准k-ε湍流模型,采用非结构化网格和SIMPLEC算法对白鹤发电厂二期工程取水泵房进水间流道进行优化计算,并对进水间前导流板角度变化时流态变化进行比较计算,确定较优的导流角,增强泥浆泵的排沙效果.计算结果表明当前导流板角度为30o和后导流板角度为35o时有较好的流态,此时流道底板附近流速较大,并且整个流道内有较强烈的湍动流产生,大部分泥沙可以达到冲淤平衡.对多泥沙河流泵房取水间的设计、运行及维护有一定的参考价值.

| Abstract: | This paper, based on the Navier-Stokes equations and the standard k-ε turbulence model, uses unstructured grid and SIMPLEC algorithm to optimize and calculate the water intake pump house water channels of second phase project of Baihe power plant, compares the calculation of the flow regime when the former guiding angle is changed, explores a better guiding angle and enhances the desilting effect of mud pump. The calculation results show that when the former guiding angle of 30° and the hind guiding angle of 35° have better flow regime, velocity near the flow channel floor is larger, and the entire flow is relatively strong turbulent flow in the water channel, most of sediment erosion and deposition can reach a balance. |
