Long-scale evolution of thin liquid films
TL;DR: In this article, a unified mathematical theory is presented that takes advantage of the disparity of the length scales and is based on the asymptotic procedure of reduction of the full set of governing equations and boundary conditions to a simplified, highly nonlinear, evolution equation or to a set of equations.
Journal ArticleDOI
Stability of symmetric and unsymmetric thin liquid films to short and long wavelength perturbations
TL;DR: In this paper, the stability of thin (100 nm) symmetrical and unsymmetrical membranes, assimilated with viscous liquids, to short and long wavelength perturbations is investigated.

An Analytical Nonlinear Theory of Thin Film Rupture and Its Application to Wetting Films
Ashutosh Sharma,Eli Ruckenstein +1 more
TL;DR: In this article, a formalism is developed to investigate the instability and the time of rupture of thin films which are subjected to finite amplitude perturbations, and the analytical expressions for a thin film devoid of surfactants are in good agreement with the numerical calculations of Williams and Davis.
Journal ArticleDOI
Instability, self-organization and pattern formation in thin soft films.
TL;DR: This article classify the instability of a thin polymer film into three broad categories, which are: instability of an ultra-thin (<100 nm) viscous film engendered by amplification of thermally excited surface capillary waves due to interfacial dispersive van der Waals forces, and instability arising from the attractive inter-surface interactions.
Journal ArticleDOI
Nonlinear evolution equations for thin liquid films with insoluble surfactants
TL;DR: In this article, the authors derived asymptotically from the full Navier-Stokes equations for free films and incorporated the effect of van der Waals attraction, capillary forces and Marangoni forces due to gradients of surface tension.

Spontaneous rupture of thin liquid films
Eli Ruckenstein,Rakesh K. Jain +1 more
TL;DR: In this paper, a small perturbation applied to the free interface generates motions in the film, and the assumption is made that the Navier-Stokes equations can be used to describe them.

Hydrodynamics of thin liquid films
Ivan B. Ivanov,D. S. Dimitrov +1 more
TL;DR: In this article, the influence of surface viscosity on the rate of thinning and on the critical thickness of rupture of foam films has been studied and it is shown that this effect depends strongly on the length-scale of the flow.
Journal ArticleDOI
Effect of surfactant concentration on the critical thicknesses of liquid films
TL;DR: In this paper, it is shown that an increase in surfactant concentration at first causes the critical thicknesses of rupture on microscopic films to decrease but gradually a nearly constant value is reached.

Destabilization of aqueous films on silica by nonionic surfactant
M.P Aronson,H.M Princen +1 more
TL;DR: In this paper, the influence of octaethyleneglycol dodecyl ether on both the contact angle and film thickness of water on polished fused silica was studied and it was found that the ability of the surfactant to produce dewetting depended extensively on the chemical (pH) and thermal history of the silica surface.
