A quantitative analysis of double-sided surface waviness on TEHL line contacts
Tribology International, 2023 In this paper, the effects of double-sided surface waviness on Thermo-Elastohydrodynamic Lubrication (TEHL) in line contacts are investigated deterministically through numerical simulations. The effects of surface amplitude, wavelength, relative position, and slide-to-roll ratio have been studied.
