Numerical analysis of Reynolds equation for gas lubrication at a high .LAMBDA. region.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1986 In this paper, a new scheme is presented for solving the Reynolds equation for gas lubrication at a high Λregion by the direct numerical solution method. This scheme derives from the concept that Poiseuille flow has an elliptical property and Couette flow has a parabolic one.

Derivation of the Reynolds type equation with memory effects, governing transient flow of lubric
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 a linear connection between velocity and pressure gradient. Our law tends to the classical Reynolds
