网格反应池局部流场的数值模拟

Numerical simulation of the localized flow field of grid reaction pool

基于N-S方程和标准k—ε模型,应用有限元分析软件ANSYS的CFD功能,在不同网格参数下对反应池局部流场进行模拟,得到不同的流动现象,对部分参数进行分析,结合微涡旋理论,对参数影响大小进行比较。

Based on N--S equation and standard κ-ε model, the localized flow field of grid reaction pool under different parameters have been simulated by using CFD function of finite element analysis software ANSYS and obtained the variable flow phenomena. Combined with the micro vortex theory, some parameters have been analyzed and compared their effects.
