| 摘 要： | 利用计算流体动力学（CFD）模拟SK静态混合器中液液两相流动。采用欧拉模型中的代数滑移混合模型（ASM），预测通过混合元件的压降、速度场和两相的体积分数分布。拉格朗日方法被用来追踪静态混合器中离散相的运动轨迹，用粒子的运动轨迹来分析混合的停留时间。

| Abstract: | Two-phase flow in SK static state mixer was simulated by calculation flow mechanics （CFD）. The algebraic slippage commixture model in Euler model （ASM） was adopted to forecast the pressure drop, velocity field and two-phase volume fraction during passing the mixing element.Lagrange method was used to track the motion trajectory of discrete phase in the static state mixer, then mixing residence time was analyzed by particle motion trajectory. |
