On Fluid/Wall Slippage

Certain (nonpolymeric) fluids show an anomalously low friction when flowing against well-chosen solid walls. We discuss here one possible explanation, postulating that a gaseous film of small thickness h is present between fluid and wall. When h is smaller than the mean free path l of the gas (Knudsen regime), the Navier length b is expected to be independent of h and very large (micrometers).

• Influence of the enclosed fluid on the flow over a microstructured surface in the Cassie state (2013, background): “In previous work, this effect has at most be treated qualitatively based on scaling arguments (Vinogradova 1995; de Gennes 2002; Ybert et al. 2007) or on considering the structured surface as a gas layer (Busse et al. 2013).”
