摘　　要：利用CFD软件ANSYS 14.0及欧拉-欧拉多相流模型,模拟了一种采用微孔曝气器的新型气升式环流反应器的气液两相流动,得到反应器内气含率和循环液速等参数的详细分布。模拟结果表明:新型气升式环流反应器的平均气含率与气量成正比关系;气量为2.5 m3/h时具有更高的循环液速。The gas-liquid flow in new air-lift loop reactor with micro-aerator the reactor was simulated.The detailed distribution of parameters,such as the local gas holdup and circulating liquid velocity,were obtained by using the commercial computational fluid dynamics software ANSYS 14.0 and Euler-Eulerian multiphase flow model.The simulation results show that the average gas holdup is proportional to air flow in the new air-lift loop reactor;When air flow is 2.5 m3 / h,it has higher circulating liquid velocity.
