摘　　要：采用计算流体动力学(CFD)的方法,以双螺旋静态混合器以及瑞士苏尔寿SX型静态混合器为主要对比分析模型,以甲醇、PVA、NaOH溶液为介质分析了二者的内部流场,通过仿真模拟计算和后处理分析,显示了物料通过两种不同叶片被动搅拌之后,在出口截面上各组分浓度分布的差异性,为今后的静态混合器的结构优化及选型提供有利的参考依据。Using the method of computational fluid dynamics（CFD）, with the double helix static mixer and the Swiss city life of SX type static mixer as main analysis model, with methanol, PVA, NaOH solution for both of the internal flow field analysis of medium, through the simulation calculation and post-processing analysis, shows the material through two different blades passive, the differences of concentration distribution of components on the exit, for the future of the static mixer structure optimization and provide beneficial reference for selection.
