一串变形液泡在管中的流动

Flow of a Train of Deformable Fluid Particles in a Tube

我们使用边界积分法求解一串液泡在管中的运动·当液泡在管中运动，总的正压力不再是常数，这一力使液泡变形和加长·我们发现变形液泡和球状液滴（具有同样的相当直径）运动的速度是不一样的，它随着液泡间距的减小而增加·间距Ｌ′／ａ′对提高速度的影响大于毛细准数的影响·速度的增长随着液泡直径的减少而变得不明显·

n the article, the boundary integral technique is used to solve the hydrodynamic movement of a train of defomable fluid particles in a tube. When a fluid particle is in a tube, the total normal stress difference is not constant any more, this force tends to distend and elongate the particle. We find that the difference between the velocity of a defomale fluid particle and a sphere (with the same radius) increases as the distance between the particles decreases, and that the increase in velocity with L′/a′ is greater the capillary number, and this increase becomes less pronounced as radius decreases.
