摘　　要：利用计算流体力学(CFD)软件Fluent及欧拉--欧拉双流相模型对两种进料管不同的气升式生物反应器内流场进行数值模拟。通过对仿真出的液相速度云图、速度矢量图及气含率云图的分析,得到了这两种反应器内气液二相的流动情况,并发现双进料管气升式生物反应器有更好的混合传质性能。CFD在气升式反应器的优化与放大方面具有重要的指导意义。The fluid flow field in two air-lift bioreactors with different feed pipes is numerically simulated using CFD software Fluent and Euler-Euler dual-flow phase model.Through the analysis of the simulated liquid velocity cloud diagram,velocity vector diagram and gas content cloud diagram,the gas-liquid two-phase flow conditions in the two reactors were obtained,and it was found that the dual-feed tube airlift bioreactor Better mixed mass transfer performance.CFD has important guiding significance in the optimization and scale-up of airlift reactors.
