摘　　要：利用CFD软件ANSYS 14.0及欧拉-欧拉多相流模型,模拟不同高径比、环隙比下气升式环流反应器的气液两相流动,得到反应器内循环液速和气含率等参数的详细分布。对比模拟结果表明,高径比为7,环隙比1时,反应器具有最优流化状态。CFD在气升式环流反应器的结构优化具有明显的指导意义。CFD software ANSYS 14.0 and Euler-Eulerian multiphase flow model are applied to simulate gas-liquid flow in airlift loop reactor with different height to diameter ratio and different annular ratio.The detailed distribution of internal circulation liquid velocity and gas holdup of the reactor are obtained by the simulation.The simulation results show that fluidized state of the reactor is the best when height to diameter ratio is 7 and annular ratio is 1.CFD is very significant in the structure optimization of airlift loop reactor.
