摘　　要：利用Ｃｒｏｗｅ和Ｓｍｏｏｔ分散颗粒群轨道模型，对直立弯道内弧形百叶窗气固分离效果进行了数值分析，探索了一种可用于此类稀薄气固两相流复杂流场计算的数学模型，结果表明，这种数值模拟是可行的，能够揭示弧形百叶窗独特的分离机理。Numerical study of the particle cllection characteristics of an arc louver separator invertical bend has been made by using Crowe and Smoot’s particle group trajectory model.Amathematical model applicable for caiculating such complicated dilute gas-solid two-phaseflow is first suggested in this paper.The numerical results show that the present numericalsimulation is feasible ,which can reveal the unique separation mechanism pertinent to the arclouver separator.
