An Analysis of Starved EHL Point Contacts with Reflow
Tribology Online, 2015 In the starved lubrication regime, the film thickness can be much less than the fully flooded film thickness. The film thickness reduction is related to the inlet meniscus distance.

Equilibrium helium film in the thick-film limit [PDF]
Low Temperature Physics, 2003 There are still some open questions about how the thickness of a liquid or solid quantum film, such as liquid helium or solid hydrogen, develops in certain limits. One of these is the thick-film limit, i.e., the crossover from the thick film to the bulk.

Film forming behavior in thin film lubrication at high speeds
Friction, 2017 The film forming condition may transit into thin film lubrication (TFL) at high speeds when it is under severe starvation. Central film thicknesses and film thickness profiles are obtained via a technique of relative optical interference intensity. These
