【摘要】 对微重力下不变形双滴的非定常热毛细迁移运动进行了数值模拟,采用了有限差分方法对动量方程和能量方程进行离散,使用波前追踪法捕捉运动的不变形液滴界面.研究显示双滴的排列方式对它们的迁移规律和相互作用影响很大,其中影响任一个液滴运动的最主要的因素是另一个液滴的存在所引起的温度场的扰动.更多还原

【Abstract】 A numerical study on interactions of two spherical drops in thermocapillary migration in microgravity was presented.Finite-difference methods were adopted and the interfaces of drops were captured by the front-tracking technique.It is found that the arrangement of drops directly influences their migrations and interaction,and that the motion of one drop is mainly determined by the disturbed temperature field because of the existence of another drop.更多还原
