摘 要: 采用有限体积法和SIMPLE算法对某污水厂初沉池集气罩内的三维湍流进行了模拟。研究了进风口的形式、位置、尺寸以及排风口的位置等因素对速度场的影响。通过对几种不同形式流场流动特性的分析,得出了一些定性的结论。 Simulates the 3-D air turbulent flow in gas-collecting hood of primary settling tank of a sewage treatment plant with finite volume method and SIMPLE algorithm. Studies the effect of several factors, including shape, location and sizes of inlets, and location of outlets etc, on the velocity fields. Draws some qualitative conclusions according to the analysis of flow characteristics of different flow fields.
