Magnetohydrodynamic Theory of Lubrication

The Physics of Fluids, 1962
The magnetohydrodynamic theory of the two-dimensional flow between plane walls of small inclination is applied to the problem of lubrication of bearings. Equations are given for boundary conditions. The arrangement of guide surface and slide block in relation to the external magnetic field are shown.

Lubrication Theory for Micropolar Fluids

Journal of Applied Mechanics, 1971
The equations governing the flow of a fluid with rigid, spherical substructure are summarized. A two-dimensional flow field is considered and applied to the geometry of a slider bearing. Order-of-magnitude arguments are used which reduce the governing equations to a system of coupled, linear, ordinary differential equations.

Theory of viscoelastic lubrication

Tribology International, 2014
Abstract We study the lubricated (wet) contact mechanics of a smooth hard cylinder sliding on a randomly rough nominally flat surface of a linear viscoelastic solid. We calculate the rolling and sliding friction, and study the transition from the boundary lubrication to the elasto-hydrodynamic lubrication regime.

Theory of Lubrication

2023
Abstract This chapter reviews the basic theory of lubrication in the context of metal forming applications. It discusses the rheological properties of fluids and their effect on fluid-film thickness at pressures, temperatures, and loading conditions typical of metal working processes. It describes the three lubrication regimes (boundary,

On weeping lubrication theory

Zeitschrift für angewandte Mathematik und Physik ZAMP, 1969
Der Einfluss einer bewegten Last auf einen zusammengesetzten Korper wird untersucht. Dieser besteht aus einer poroselastischen Schicht auf einer elastischen Halbebene. Das Modell simuliert die mechanische Belastung eines hyalinen Knorpels endlicher Dicke, der die Oberflache von Knochengelenken bedeckt.
