Film Collapse in EHL and Micro-EHL [PDF]

open access: yesJournal of Tribology, 1991
The pressure, film thickness, and streamline patterns within the lubrication conjunction in elastohydrodynamic and microelastohydrodynamic lubrication are presented for various operating parameters. The circular non-Newtonian fluid model was used and periodic stationary surface irregularities were considered.
