Reynolds equation and elastohydrodynamic lubrication in metal seals

Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences, 1976
Abstract Oil film profile and pressure distribution between a metal seal and a reciprocating hydraulic jack rod have been measured. A rapidly diverging oil film, which would normally be expected to cause rupture of the fluid and severe cavitation, was observed near the centre of the contact, but the corresponding pressure in this ...

Generalized Reynolds equation and variational inequality in lubrication theory

Applied Mathematics and Mechanics, 1982
This paper has derived generalized Reynolds equation in lubrication theory in terms of tensor analysis and S-coordinate system, and has provided corresponding variational inequality. The curved effect of flow of lubricant fluid is considered, and the influence of intrinsic properties of surfaces of axis and axle sleeve on flow are counted.

A Reynolds-Eyring Equation for Elastohydrodynamic Lubrication in Line Contacts

Journal of Tribology, 1987
A new Reynolds equation, based on the Eyring theory of non-Newtonian flow, is derived for flow in one dimension. It is shown that this new equation reduces to the traditional Reynolds equation as the Eyring model approaches the Newtonian model in the limit. Numerical solutions are presented for a selected oil at two different temperatures.

High-pressure rheology of lubricants and limitations of the Reynolds equation

Tribology International, 1998
Abstract A review of high pressure rheology leads to the conclusion that the results from rheometers may be used to generate empirical rate equations which are useful in modelling elastohydrodynamic traction. However, an analytical treatment of piezoviscous liquids reveals that the Reynolds equation adequately captures the mechanics of the ...

Generalized Reynolds Equation for Stochastic Lubrication and its Application

Journal of Mechanical Engineering Science, 1975
By using the theory of a stochastic process, a generalized form of Reynolds equation applicable to rough bearings is derived by assuming the fluxes to be represented by power series of a stochastic film-thickness function. In the case of a step slider bearing, it is shown that load capacity and friction force increase but that coefficient of friction

On the Solution of the Reynolds Equation for Slider-Bearing Lubrication—I

Journal of Fluids Engineering, 1952
Abstract An exact solution is developed for the Reynolds equation in the hydrodynamical theory of slider-bearing lubrication with side leakage for film thickness varying exponentially. This solution is in the form of a rapidly convergent series from which calculations for the pressure distribution, total bearing load, and center of ...

On micropolar fluids in the theory of lubrication. Rigorous derivation of an analogue of the reynolds equation

International Journal of Engineering Science, 1996
We derive, for micropolar fluids, an analogue of the classical Reynolds equation of the theory of lubrication, and then discuss its particular forms depending on the assumptions imposed on both the viscosities and the data.

Generalized One-Dimensional Reynolds' Equation for Micropolar Fluid Film Lubrication

International Journal of Nonlinear Sciences and Numerical Simulation, 2002
Summary: This paper presents a theoretical study of some basic lubrication problems with micropolar fluids as lubricants. A generalized modified classical one-dimensional Reynolds' type equation for micropolar fluid film lubrication has been derived. This equation shows that the boundary condition on the spin makes the fluid to behave as a classical ...

A generalized Reynolds equation for fluid-film lubrication

International Journal of Mechanical Sciences, 1962
Summary In the analysis of fluid-film bearings the basic equation employed is known as the Reynolds equation. This equation, which governs the generation of pressure in the lubricant film, is encountered in numerous forms each applicable to a particular set of circumstances only.
