| 摘 要： | 运用晶格玻尔兹曼方法研究了两个颗粒在Poiseuille流中的运动行为.分析了颗粒直径和管道直径之比d/D对颗粒相互作用的影响;讨论了颗粒的水平距离、颗粒的平衡位置与颗粒直径之间的关系.研究发现当d/D小于0.5时,颗粒的水平距离稳定在4.2倍的颗粒直径左右.研究对于理解多颗粒系统中颗粒之间的相互作用等具有一定的价值.

| Abstract: | The moving behaviour of two particles in a pressure-driven flow is studied by the lattice Boltzmann simulation in two dimensions.The effect of blockage ratio on particles motion is investigated numerically.The x-directional distance between the particles and the particles equilibrium positions for different particle diameters are discussed.The simulation results show that x-directional distance is almost 4.2 times of the particle diameter if the blockage ratio is less than 0.5.The simulation results are helpful in understanding the particle-particle interaction in suspensions with swarms of particles. |
