摘　　要：针对颗粒在密相输送过程中经常会出现的堵塞问题,运用气固两相流动理论中的欧拉—欧拉模型和湍流模型,使用流体有限元软件Fluent,对L型管道中的颗粒浓度分布规律进行数值模拟。分析和讨论气体风速、进口处颗粒的体积含量对L型管道内颗粒浓度分布以及出口处颗粒速度的影响。The Euler-Euler model and turbulent model in the theory of gas-solid two-phase flow are used in this paper to deal with plugging which often appears in dense phase conveying process.The rule of the concentration of traditional Chinese medicine granules within L-type pipeline is numerically simulated by using the Fluent software to do the finite element analysis.Then the influences of the velocity of gas and the initial volume of particles on the concentration distribution inside the L-shaped pipe and particle velocity at the exit are analyzed and discussed.
