Thumbs up And in other news, why water is not wet [all the time]! [FREE]

Quote:
The maximum speed at which a liquid can wet a solid is limited by the need to displace gas lubrication films in front of the moving contact line. The characteristic height of these films is often comparable to the mean free path in the gas so that hydrodynamic models do not adequately describe the flow physics. This Letter develops a model which incorporates kinetic effects in the gas, via the Boltzmann equation, and can predict experimentally observed increases in the maximum speed of wetting when (a) the liquid’s viscosity is varied, (b) the ambient gas pressure is reduced, or (c) the meniscus is confined.
