Tribol., 132 (3), pp. 031501) that focused on model development and validation, as well as investigation of fundamental PEHL mechanisms in smooth surface contacts. This part of the study is mainly on the PEHL behavior involving simple surface...

...Punit Kumar; M. M. Khonsari An extensive set of full elastohydrodynamic lubrication point contact simulations has been used to develop correction factors to account for the effect of shear-thinning lubricant behavior on the central and minimum film thickness in circular contacts under pure rolling...

... in wavelength or the decrease in waviness amplitude, the cyclic solution can approach the steady-state solution gradually. Such a comparison also suggests that, in general, the existence of surface waviness is harmful to an EHL point contact, although it may be beneficial in a contact pair composed of two...

...Wen-Zhong Wang; Yu-Chuan Liu; Hui Wang; Yuan-Zhong Hu This paper presents a transient thermal model for mixed lubrication problems in point contacts. The model deterministically calculates pressure and surface temperature by simultaneously solving a system of equations that govern the lubrication...
