通气式中心龙卷流搅拌槽内气-液两相流的混合特性

Research on Mixing Characteristics in A Ventilated Central Tornado Flow Stirring Tank

运用计算流体动力学(CFD)方法对单通管桨搅拌槽和双通管搅拌槽内部流场进行数值模拟,考察了流体在在单通管和双通管搅拌槽内宏观流动场的效果。研究发现,流体在双通管内部流场流动效果好。在此基础上可以看出,通气式搅拌槽开两个孔比开一个孔效果好,这对搅拌槽的优化设计和工业放大效应有一定的实际意义。

The research of the flow simulation in the inner stirring tank with the single pipe and dual pipe was studied by CFD, which had demonstrated the fluid simulation effect of the single pipe and dual pipe. It was found that the effect was better in the single pipe stirring tank than the dual pipe one. Basing on this result, the flow simulation effect of dual pipe was better than the single one, good, which had certain practical significance effect in industry.
