液滴偏心碰撞的多体耗散粒子动力学研究
A Many-Body Dissipative Particle Dynamics Study of Droplets Eccentric Impacting on Fi-ber
摘要: 液滴碰撞细杆的现象在日常生活中随处可见，本文采用了多体耗散粒子动力学(MDPD)模拟液滴以不同角度偏心碰撞圆柱形杆，研究了不同碰撞速度，不同碰撞角度以及不同偏心率对于液滴薄片比例和临界速度的影响。结果表明，分裂滴落的临界速度随着偏心率增大先减小而后增大，不同角度下，临界速度的改变趋势类似，接触细杆的临界速度随着偏心率增大而减小。
Abstract: The phenomenon of droplet impacting on the fiber can be seen everywhere in our daily life. In this paper, we use Many-body Dissipative Particle Dynamics (MDPD) to simulate the droplet eccentric collision with a fiber at different angles. The results show that the critical velocity of splitting drop-ping decreases first and then increases with the increase of eccentricity. The changing trend of crit-ical velocity is similar at different angles, and the critical velocity of contacting fiber decreases with the increase of eccentricity.
