| 中文摘要: |
| 由于对大型双层侧进式搅拌槽进行实验方法研究比较困难，采用数值模拟的方法对其进行研究。利用计算流体
动力学( CFD)，通过gambit建立模型并划分网格，利用Fluent软件进行计算求解，探讨不同转速下的固相分布情况，临界
离底悬浮转速、颗粒直径对临界悬浮转速的影响。结果表明固相颗粒主要分布在搅拌槽底部和双层搅拌器之间的区域，
在搅拌槽的上部区域形成一个明显的清液层，双层侧进式搅拌器的使用可以有效地减少由于提高搅拌转速而增加的密
封难度和功率消耗。 |

| Due to the difficulty of experiment for large double side entering agitation tank. numerical simulation method
was used. Through computational fluid dynamics ( CFD) . the model was set up and grid was divided by Gambit,
solution was calculated by fluent. The solid phase distribution with different speeds, the critical suspension speed of
impeller, and the influence of particle diameter on critical suspension speed were investigated. The results show that the
solid particles are mainly distributed between tank bottom and double stirrer. a clear liquid layer is formed on the upper
part of the tank. double side entering agitator can effectively reduce increased sealing difficulty and power consumption
due to the increase of stirring speed. |
