| 摘 要： | 本文首先用离散涡方法对绕圆柱和半无限长平板的流动作了数值模拟。在讨论粒子和涡团耦合运动的基础上首次提出了粒子在流场中运动的拟涡位移模型,并对几个典型的气粒两相流动作了数值模拟。文章最后对流场中粒子运动的瞬时状态作了统计处理,得到了关于粒子在流场中分布的概率密度函数和粒子脉动速度的分布函数并用拟涡位移模型对壁面附近粒子的运动－沉积和反弹作了数值模拟。计算结果是令人满意的。

| Abstract: | A new model named 'vortex-particle coupling' for the simulation of fine particle dispersion in flow field is developed and applications to several particulate flows are carried out with Largrange method. This model gives a rather simple way to get instantaneous parameters of particles in flow field. Several typical examples are given here. The numerical results show that the use of this new model in the simulation of particulate flow is successful. |
