Moving contact lines, wetting transitions and interfacial instabilities in confined environments
… base state of the invading thin films to be an undercompressive shock, which has previously been shown to lead to stable fronts. Using linear stability analysis and nonlinear simulations, we show that consistent with our experimental observations the thin film front in a Hele-Shaw cell is …

Nonlinear long-wave interfacial stability of two-layer gas-liquid flow
… nonlinear case, admissible criteria for Lax shocks, undercompressive shocks and rarefaction waves are investigated. Through a numerical verification we find that these criteria do not depend significantly on the inertial effects within the more dense layer. The choice of the local/nonlocal …

Derivation of an Evolution Equation for Two-Dimensional Waves on Thin Films
We examine wave propagation on thin liquid films subjected to gravity, fluid friction, surface tension, and Marangoni effects. The physical configuration is a thin liquid layer on a planar incline. Following previous studies, the Marangoni effect is incorporated by a constant surface tension …
