蒸发锋中的局部瑞利不稳定性
Localized Rayleigh Instability in Evaporation Fronts
摘要:
一个定性的不同表现的瑞利不稳定性的证明,而不是通常的扩展波动和分裂成许多液滴的液体,不稳定性是本地化的,导致一个孤立的缩小的液体细丝。局部不稳定性,引起的不均匀曲率的液体域,起着关键的作用,在蒸发薄液膜的固体表面。
英文摘要:
A qualitatively different manifestation of the Rayleigh instability is demonstrated, where, instead of the usual extended undulations and breakup of the liquid into many droplets, the instability is localized, leading to an isolated narrowing of the liquid filament. The localized instability, caused by a nonuniform curvature of the liquid domain, plays a key role in the evaporation of thin liquid films off solid surfaces.
