Bound-state formation in interfacial turbulence: direct numerical simulations and theory
(2013)We examine pulse interaction and bound-state formation in interfacial turbulence using the problem of a falling liquid film as a model system. We perform direct numerical simulations (DNSs) of the full Navier-Stokes equations ... -
Extreme solitary waves on falling liquid films
(2014)Direct numerical simulation (DNS) of liquid film flow is used to compute fully developed solitary waves and to compare their characteristics with the predictions of low-dimensional models. Emphasis is placed on the regime ... -
The primary instability of falling films in the presence of soluble surfactants
(2013)We investigate the linear stability of a film flowing down a solid substrate in the presence of soluble surfactants. The Navier-Stokes equations for the liquid motion are considered, together with advection-diffusion ... -
The role of surfactants on the mechanism of the long-wave instability in liquid film flows
(2014)The analysis for the physical mechanism of the long-wave instability in liquid film flow is extended to take into account the presence of a surfactant of arbitrary solubility. The Navier-Stokes equations are supplemented ... -
Short- to long-wave resonance and soliton formation in boundary-layer interaction with a liquid film
(2010)Dynamic interaction between a boundary layer of air and a liquid film is investigated in this paper. The low air-to-film-viscosity ratio is considered in which case the boundary layer is quasi-steady on the time scale ...
