摘　　要：利用计算流体力学(CFD)软件Fluent,以多重参考系法对发酵行业中的发酵罐搅拌流场进行整体数值模拟。基于标准的κ-ε紊流模型模拟了发酵罐内的流场分布,分析了垂直面和水平面上液相流的流场分布及规律,可为搅拌器的结构设计提供参考。Using CFD software Fluent, the whole numerical simulation for agitated flow field of fermenter in fermentation industry was carried out by multiple reference frame method. Based on standard κ-ε turbulence model, flow field distribution of fermenter was simulated, flow field distribution and rules of liquid flow at vertical and horizontal plane was also be analyzed, which could provided reference for structure design of agitator.
