Nonlinear Reynolds equation for hydrodynamic lubrication [PDF]
Applied Mathematical Modelling, 2015 We derive a novel and rigorous correction to the classical Reynolds lubrication approximation for fluids with viscosity depending upon the pressure. Our analysis shows that the pressure dependence of viscosity leads to additional nonlinear terms related to the shear-rate and arising from a non negligible cross-film pressure.

Formulation of the Reynolds equation on a time-dependent lubrication surface [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016 The Reynolds equation, which describes the lubrication effect arising through the interaction of two physical surfaces that are separated by a thin fluid film, is formulated with respect to a continuously evolving third surface that is described by a time-dependent curvilinear coordinate system.

Existence and Uniqueness of Solutions to the Compressible Reynolds Lubrication Equation [PDF]
SIAM Journal on Mathematical Analysis, 1986 We prove the existence of a solution to the compressible Reynolds lubrication equation and we show that our solution is unique in the class of nonnegative solutions (under some additional hypotheses, we prove that our solution is unique among all weak solutions). We also prove the strong result that the mapping from the boundary data to the solution is

Derivation of the Reynolds type equation with memory effects, governing transient flow of lubric [PDF]
Glasnik matematički, 2004 In this paper we derive the Reynolds type lubrication equation with memory effects for lubrication of a rotating shaft. Starting from the nonstationary Stokes equations and using the asymptotic expansion we obtain a law that is nonlocal in time and gives

CFD Investigation of Reynolds Flow around a Solid Obstacle
Lubricants, 2022 The Reynolds equation defines the lubrication flow between the smooth contacting parts. However, it is questionable that the equation can accurately anticipate pressure behavior involving undeformed solid asperity interactions that can occur under severe

The Compressible Reynolds Lubrication Equation [PDF]
, 1987 We give a general derivation of the Reynolds lubrication equation. We then state and sketch the proofs of some of the authors’ recent results concerning the existence, uniqueness, and qualitative behavior of solutions to the compressible Reynolds lubrication equation. Finally, we give an application of our results to a problem in elastohydrodynamics.
