We present an analytical and numerical study of the two-dimensional capillary-driven thin-film equation. In particular, we focus on the intermediate asymptotics of its solutions. Linearising the equation enables us to derive the associated Green’s function and therefore obtain a complete set of solutions. Moreover, we show that the rescaled solution for any summable initial profile uniformly converges in time towards a universal self-similar attractor that is precisely the rescaled Green’s… 

Universal self-similar attractor in the bending-driven levelling of thin viscous films

We study theoretically and numerically the bending-driven levelling of thin viscous films within the lubrication approximation. We derive Green’s function of the linearized thin-film equation and

Approach to universal self-similar attractor for the levelling of thin liquid films.

The capillary levelling of a random surface perturbation on a thin polystyrene film is compared with a theoretical study on the two-dimensional capillary-driven thin film equation and it is shown that the surface profiles present long term self-similarity, and furthermore, that they converge to a universalSelf-similar attractor that only depends on the volume of the perturbations, consistent with the theory.

Relaxation and intermediate asymptotics of a rectangular trench in a viscous film.

This work reports on full agreement between theory and experiments for the capillary-driven flow and resulting time dependent height profiles, a crossover in the power-law dependence of the viscous energy dissipation as a function of time as the trench evolution transitions from two noninteracting to interacting steps.

Capillary levelling of a cylindrical hole in a viscous film.

The capillary levelling of cylindrical holes in viscous polystyrene films was studied using atomic force microscopy as well as quantitative analytical scaling arguments based on thin film theory and

Nanobubble-induced flow of immersed glassy polymer films

We study the free-surface deformation dynamics of an immersed glassy thin polymer film supported on a substrate, induced by an air nanobubble at the free surface. We combine analytical and numerical

Intermediate asymptotics on crossover of scaling law on dynamical impact of viscoelastic surface

In this paper, a crossover of scaling laws is described as a result of the interference from selfsimilar variable of the higher class of the self-similarity on the dynamical impact of solid sphere

Flow in thin polymer films: molecular structure, initial conditions, and boundary conditions

Surface tension driven flow is studied in films of viscous polymer liquid by monitoring the spreading of droplets or the capillary levelling of films with excess surface area. The research presented

This is a ‘sandwich thesis’ consisting of a publication that I contributed to during my M.Sc. work. The thesis begins with an introduction section in Chapter 1 that discusses the relevant physical

Elastocapillary levelling of thin viscous films on soft substrates

A thin liquid film with non-zero curvature at its free surface spontaneously flows to reach a flat configuration, a process driven by Laplace pressure gradients and resisted by the liquid's

Numerical solutions of thin-film equations for polymer flows

This work reports on the numerical implementation of thin-film equations that describe the capillary-driven evolution of viscous films, in two-dimensional configurations, and focuses on two particular cases inspired by experiments: the leveling of a step at the free surface of a polymer film, and the levelingof a polymer droplet over an identical film.

The Linear Limit of the Dipole Problem for the Thin Film Equation

Investigating self-similar solutions of the dipole problem for the one-dimensional thin film equation on the half-line yields a surprisingly rich set of stable solutions for the intermediate asymptotics of this problem.

Capillary-driven flow induced by a stepped perturbation atop a viscous film

Thin viscous liquid films driven by capillarity are well described in the lubrication theory through the thin film equation. In this article, we present an analytical solution of this equation for a

Self-similarity and energy dissipation in stepped polymer films.

The results of experiments indicate the effectiveness of stepped polymer films to elucidate nanoscale rheological properties and derive a master expression for the time dependence of the excess free energy as a function of the material properties and film geometry.

Instabilities in Gravity Driven Flow of Thin Fluid Films

This paper presents theoretical, computational, and experimental aspects of the instability development in the flow of thin fluid films, and derivation of the thin film equation using lubrication approximation is presented.

Positivity-Preserving Numerical Schemes for Lubrication-Type Equations

Stability and convergence of both positivity-preserving and generic methods, in one and two space dimensions, to positive solutions of the PDE, are proved, showing that the generic methods also preserve positivity and have global solutions for sufficiently fine meshes.

Reduced interfacial entanglement density affects the boundary conditions of polymer flow.

Evidence is given that merely a slip-boundary condition at the solid-liquid interface can lead to an asymmetric profile, and variation of molecular weight shows that slippage is directly linked to chain entanglements.

Surface diffusion currents and the universality classes of growth.

We show, through simulations of a variety of one- and two-dimensional solid-on-solid models, that nonequilibrium surface diffusion processes in the presence of a deposition flux are generically

Flattening of a Nearly Plane Solid Surface due to Capillarity

The relaxation of a nearly plane surface to flatness is discussed under the assumption that all surface properties are independent of orientation. A general solution is obtained for the combined
