摘　　要：采用Fluent软件,选取SKE/DRSM湍流模型,对1000/700无压给料三产品重介质旋流器的流场进行了数值模拟.通过对无压给料三产品重介质旋流器流场的三维速度、压强、密度和空气柱的数值模拟研究,对无压给料三产品重介质旋流器内的流场有了更深入和细致的了解,得到了几点有意义的结论.数值模拟研究结果表明,Kesall导出的旋流器内液流径向速度分布至少对于DWP和DSM结构的旋流器是不适合的.Based on SKE/DRSM turbulent flow model in Fluent, the numerical simulation of the flow fields in the gravity-fed 3-product H. M. cyclone with diameter of 1 000/700 mm was made. What＇ s more, the three-dimensional velocity, density and pressure distribution of the flow field in the gravity-fed 3-product H. M. cyclone were studied as well, some conclusions were summarized. The results obtained from the numerical simulation indicate that radial velocities distribution by Kesall is unsuited to DWP and DSM cyclone.
