摘要
本文在直接数值模拟混合层流场的基础上,求解柱状粒子运动方程而得到粒子运动轨迹,说明粒子在混合层中的不同区域,其运动轨迹也不同,有的呈现波状轨迹,有的呈现环状轨迹,有的是混合轨迹。粒子的混合程度与St数有关。文中结论对工程应用有指导意义。
Based on the numerical simulation of mixing layers, the motion equation of cylindrical particle is solved and the particle trajectories are given. The results show that there are different trajectories for the particles in the different regions, some particles move wavily, some ringlikely, and others are combination of both. The mixing areas depend on the particle St number. The conclusions are helpful for the applications.
