| 摘 要： | 为解决工程应用中三维流固两相流动力学建模的难题，提出了基于离散单元法(DEM)的颗粒群轨道柔性模型．即在Euler坐标系中表达流体连续相，在Lagrangian坐标系中运用DEM表达颗粒离散相，从而简单且有效地解决了三维流固两相流中颗粒相和流体相间的双向耦合和求解问题，同时以三维管道中气固两相流的建模和典型实例，可视化地说明了该方法的有效性．

| Abstract: | For dynamics modeling of 3D fluid-solids two-phase flows in engineering problem it was brought forward of particles trajectory flexible model based on the discrete element method(DEM). It meant that the fluid motion is solved in Euler model and the particle motion is calculated by DEM method in (Lagrangian) coordinates. The model simply and effectively solves the two-way coupling effect and solution (between) particles and fluid. Applying this model, the calculation successfully solves a typical problem: (simulating) fluid-dynamics of gas-solid two-phase flows in a cylindrical tube. |
