论文摘要
最近的实验结果表明，通过振荡性变形的悬浮液滴内部诱导的相互流动增强了混合[T.渡边等人。科学。 Rep。8，10221（2018）]。通常，相互流量无法以时间平均值对流溶质，而搅拌无法进行。在本文中，我们关注的扩散过程与倒流流相结合。从理论上讲，我们可以通过相互流动来增强扩散过程，并且通过用相互流动的过度阻尼的langevin方程来确认结果。
Recent experimental results indicate that mixing is enhanced by a reciprocal flow induced inside a levitated droplet with an oscillatory deformation [T. Watanabe et al. Sci. Rep. 8, 10221 (2018)]. Generally, reciprocal flow cannot convect the solutes in time average, and agitation cannot take place. In the present paper, we focus on the diffusion process coupled with the reciprocal flow. We theoretically derive that the diffusion process can be enhanced by the reciprocal flow, and the results are confirmed via numerical calculation of the over-damped Langevin equation with a reciprocal flow.
