搅拌槽内固液两相流的数值模拟及功率计算

Numerical Simulation and Power Calculation of Solid-liquid Two-phase Flow in Stirred Tank

使用计算流体动力学的方法对搅拌槽中的流场进行模拟,得到搅拌槽中液体的流动状况和体积分数分布。对流场分布规律、固体颗粒体积分数特点加以分析,进而利用模拟出的数据计算搅拌轴的功率,为搅拌器的设计提供参考。

Using computational fluid dynamics to simulate the flow field in stirred tank,the flow situation and volume fraction distribution of the liquid in stirred tank were obtained.The flow field distribution laws of liquid and the volume fraction characteristics of solid particles were analysed,and then using the date of simulation to calculate the power of agitator shaft,so as to provide reference for the design of mixer.
