Laminar film flow down a wavy incline
(1997)Laminar how of a liquid, down an inclined wall with sinusoidal corrugations, is considered. A linear analysis, valid for small-amplitude disturbances but arbitrary wavelength and Re number, leads to an Orr-Sommerfeld type ... -
Linear resonance in viscous films on inclined wavy planes
(2008)We study viscous gravity-driven films flowing over periodically undulated substrates. Linear analysis describes steady flow along small amplitude corrugations for films of arbitrary thickness. Solving the resulting system ... -
Nonlinear resonance in viscous films on inclined wavy planes
(2009)We study nonlinear resonance in viscous gravity-driven films flowing over undulated substrates. Numerical solution of the full, steady Navier-Stokes equations is used to follow the emergence of the first few free-surface ... -
Steady solutions of inertial film flow along strongly undulated substrates
(2011)Steady flow of a liquid film along sinusoidal, steeply corrugated walls is investigated by finite-element simulation of the 2D Navier-Stokes equations. Resonance between the wall and capillary-gravity waves travelling ... -
Wall-triggered interfacial resonance in laminar gas-liquid flow
(1998)Laminar gas-liquid flow through a channel with corrugated bottom, driven by a combination of gravity and pressure drop, is considered. A linear analysis, valid for small-amplitude disturbances but arbitrary wavelength and ...
