... though boundary lubrication (BL) film thicknesses are frequently many nanometers [ 32 ]. Thus, the thin-film lubrication inquiry focuses on determining the unknown range of film thickness. Additionally, to the piezo-viscous influence besides solid elastic deformation, it is commonly believed that HL...

... be attributed to its lower roughness. The surface morphology of a thin film can generally be described by a Gaussian self-affine fractal with a long wavelength cutoff. Such a model gives a surface height–height correlation function [ 33 ] of (1) C ( r ) = λ 2 exp [ - ( | r...

...Guy Bayada; Laurent Chupin; Sébastien Martin In this paper, an asymptotic expansion is used to derive a description of Phan–Tien– Tanner (PTT)/Oldroyd-B flows in the thin film situation without the classical “upper convective maxwell”(UCM) assumption. We begin with a short presentation of the Phan...
