Cover Story: Apart from complex numerical models to predict the tribological behavior of elastohydrodynamically lubricated contacts, non-dimensional similarity groups, and analytically solvable proximity equations can be used to estimate integral fluid film parameters. Based on the pioneering work of Dowson and Higginson as well as Blok and Moes, these approaches have been improved by modifications or correction factors to capture different contact geometries (line-, point-, or elliptical contacts) and to include fluid compression, thermal, non-Newtonian, starvation, or roughness effects. This review article systematically reviews these modifications/corrections and discusses their applicability as well as limitations before presenting some future research directions.
