论文摘要
本文涉及建模由于其特征长度尺度的时间和空间变化，在两个弱可溶的阶段之间的间歇性区域的演变建模。首先，对允许间歇性区域演变的更一般描述的需求是合理的。之后，以前工作的结果（WacławczykT。，2017年，关于流体，水平和相位场接口模型的关系之间的关系，Int。J。Multiphas。Flow，第97卷，第97卷），在尖锐的界面模型中已知的尖锐界面模型与文献中的液滴结合机制中认识到了Moreculacnath Interemant Dymands S. M.V.，Reese J.M.最后，在几种测试案例中引入并验证了间歇性区域也可能处于非平衡状态时，将平衡解决方案扩展到案例的物理和数值模型。
This paper concerns modeling of the evolution of intermittency region between two weakly miscible phases due to temporal and spatial variations of its characteristic length scale. First, the need of a more general description allowing for the evolution of intermittency region is rationalized. Afterwards, results of the previous work (Wacławczyk T., 2017, On a relation between the volume of fluid, level-set and phase field interface models, Int. J. Multiphas. Flow, Vol. 97) are discussed in context of the sharp interface models known in the literature and insight into droplet coalescence mechanism recently recognized in the molecular dynamics studies (Perumanath S., Borg M.K., Chubynsky M.V., Sprittles J.E., Reese J.M., 2019, Droplet coalescence is initiated by thermal motion, Phys. Rev. Lett., Vol. 122). Finally, the physical and numerical models extending applicability of the equilibrium solution to the case when intermittency region could also be in the non-equilibrium state is introduced and verified in several test cases.
