Although many tribology references have presented the Reynolds equation in cylindrical coordinates, they may not be applicable to the slipper/swash plate interface in axial piston pumps due to complex macro and micro motions of slippers.

A Nonlinear Version of the Reynolds Equation for Flow in Rock Fractures With Complex Void Geometries
Water Resources Research, 2020This study presents a nonlinear Reynolds equation (NRE) for single‐phase flow through rock fractures. The fracture void geometry is formed by connected wedge‐shaped cells at pore scale, based on the measured aperture field.

For textured surface lubrication problems, a small texture aspect ratio and a large Reynolds number can lead to strong recirculation in the textures and significant convective inertia effects. When these effects cannot be neglected, the Stokes system and

Burgers’ equation with high Reynolds number
Physics of Fluids, 1997Burgers’ equation, involving very high Reynolds numbers, is numerically solved by using a new approach based on the distributed approximating functional for representing spatial derivatives of the velocity field. For moderately large Reynolds numbers, this simple approach can provide very high accuracy while using a small number of grid points.

World Tribology Congress III, Volume 1, 2005
Exact, closed form one-dimensional Reynolds equations are presented for the Ostwald-DeWaele model, Ellis model, Spriggs model and the double-Newtonian Rabinowitsch and Ferry models. From numerical solutions for flow rate, an approximate Reynolds-Carreau equation is obtained.

On the derivation of Reynolds equation
Wear, 1962The complete Reynolds Equation in 3-dimensions is derived by three methods which differ basically in the way in which the continuity condition is applied. The apparent divisions of the mechanisms of hydro-dynamic lubrication which are suggested by these derivations, such as “wedge,” “squeeze” terms etc. are compared and it is shown that such a division

Modeling of the Reynolds Stress Transport Equation
AIAA Journal, 1997An empirical strategy for improving modeling of the energy dissipation rate e ij and the velocity-pressure gradient Π ij terms in the transport equations for the Reynolds stresses is proposed on the basis of available direct numerical simulations of the turbulent boundary layer and fully developed turbulent channel flow.

Some Exact Solutions of Reynolds Equation
Journal of Tribology, 1995In order to check the numerical analysis of Reynolds equation for gas lubricated bearings, it is desirable to have available exact analytical solutions. This note outlines the construction of some exact, two-dimensional, transient solutions for this purpose.
