本文采用Oldroyd-B模型对弹性流体中线串珠结构的动力学进行数学模拟。相对于牛顿流体而言,非牛顿流体液丝破裂过程非常缓慢。这种缓慢的破裂过程为流体提供了充足的时间显现一些有趣的现象,例如液滴的排泄和移动。通过主要作用力的总合近似分析液丝拉伸过程中的受力情况。弹性力在弹性液丝动力学中起重要作用,它显著阻碍了液丝从拉伸到排泄的变化过程。
In this paper, the Oldroyd-B model is used to simulate the dynamics of the beaded wire in elastic fluid. Compared with Newtonian fluid, non-Newtonian fluid rupture process is very slow. This slow rupture process provides sufficient time for the fluid to reveal interesting phenomena such as droplet excretion and movement. Through the main force of the approximate analysis of liquid force in the process of drawing tension. Elastic force plays an important role in the dynamics of elastic liquid wire, which significantly hinders the liquid filament from stretching to excretion.
