摘要
用三维湍流模式结合混合有限分析法对浅水型同流情况下污水排放的近区稀释特性进行了数值计算.与Parr和McGuirk的试验资料进行了对比、两者吻合较好,进而给出温度和速度的沿程变化规律以及浮力射流的分叉现象.
In this paper, the typical discharge of polluted water into rivers is studied. The 3-dimensional turbulence modelling and hybrid finite analytic method (HFAM) are used to predict the behavior of near field for buoyant jets in shallow coflowing receving waters. The effect of buoyancy is considered by mathematical mod-elling. The solutions with the HFAM agree well with the experimental data. It is very interesting that there is bifurcation in this kind flow.
