Liquid Film Dryout and Re-wetting Behavior

Thickness of residual wetting film in liquid-liquid displacement.

Core-annular flow is common in nature, representing, for example, how streams of oil, surrounded by water, move in petroleum reservoirs. Oil, typically a nonwetting fluid, tends to occupy the middle (core) part of a channel, while water forms a surrounding wall-wetting film. What is the thickness of the wetting film? A classic theory has been in existence for nearly 50 years offering a solution...

Liquid 4He on Cs : drying, depinning, and the non-wetting ‘thin-film’

Liquid 4He shows a dewetting phase on Cs and Rb at low temperatures. These are the only substrates which are not wetted by 4He. On Cs the wetting temperature, Tw, is about 2 K. Usually one observes a thick metastable helium film remaining on the Cs substrate when either the surface is cooled below Tw (so starting from a wet film) or when bulk helium (in the form of a drop or an advancing film) ...
