Experimental study of inclined film flow along periodic corrugations: The effect of wall steepness
(2006)Gravity-driven film flow along an inclined periodic wall with transverse rectangular corrugations is studied experimentally. The effect of corrugation steepness (=height/length) is considered in detail and an interesting ... -
Experiments on laminar film flow along a periodic wall
(2002)Experimental results are reported on the structure of gravity-driven film flow along an inclined periodic wall with rectangular corrugations. A fluorescence imaging method is used to capture the evolution of film height ... -
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 ... -
Measurements of liquid film flow as a function of fluid properties and channel width: Evidence for surface-tension-induced long-range transverse coherence
(2011)We study experimentally the influence of the transverse dimension on film flow in relatively wide channels with sidewalls. Large deviations from two-dimensional predictions are observed in the primary instability and in ... -
Nominally two-dimensional waves in inclined film flow in channels of finite width
(2010)Traveling waves in inclined film flow in channels of finite width are never truly two-dimensional (2D) because of a long-range effect of sidewalls The present study documents the characteristics of the first waves that are ...
