摘要
单层四叶搅拌桨小型搅拌釜是实验室常用反应设备。采用CFD数值模拟的方式,筛选了标准k-ε、RNGk-ε、SST、RSM等四种湍流模型,采用多重参考系法对小型搅拌釜的流场迚行模拟,比较不同模型的桨叶区速度场、压力场、湍流强度分布以及线速度分布等预测结果,筛选适合小型反应釜的流场模型。
The miniature stirred reactor with single-layer and four-blade agitator is commonly used in laboratories.In this paper,based on CFD numerical simulation,four turbulence models of standard k-ε,RNG k-ε,SST and RSM were used to simulate the flow field in a miniature reactor by multiple reference frame method.Different models’predicted results of velocity field,pressure field,turbulence intensity distribution and linear velocity distribution in the blade region were compared,and suitable flow field model was screened out.
