Transition from Boundary Lubrication to Hydrodynamic Lubrication of Slider Bearings

IBM Journal of Research and Development, 1974
The transition from boundary lubrication to fully hydrodynamic lubrication is investigated for air-lubricated slider bearings using the electrical resistance method. Intermittent contacts are shown to exist even under conditions for which the numerical solution of the Reynolds equation or white light interferometry predicts steady state spacings in the

On the transition from boundary lubrication to hydrodynamic lubrication in soft contacts

Journal of Physics: Condensed Matter, 2009
We consider the contact between elastically soft solids with randomly rough surfaces in sliding contact in a fluid, which is assumed to be Newtonian with constant (pressure-independent) viscosity. We discuss the nature of the transition from boundary lubrication at low sliding velocity, where direct solid-solid contact occurs, to hydrodynamic ...

On the Effect of Lubricant Inertia in the Theory of Hydrodynamic Lubrication

Journal of Basic Engineering, 1959
A theoretical study is made of the corrections required to the basic lubrication equations to allow for small effects of lubricant inertia in the laminar regime. The problem is approached by first determining the stream function for a wedge-shaped oil film with purely viscous flow and then obtaining the first-order correction for inertia.

Textured Surface Hydrodynamic Lubrication: Discussion

Tribology Letters, 2012
We discuss on a recently presented theory of textured surface hydrodynamic lubrication (Scaraggi, Phys Rev E, 2012). The model, based on the Bruggeman effective medium approach, allows to analytically evaluate the effects of a generic texture shape, distribution, and area density on the macroscopic hydrodynamic characteristics of the contact, such as ...
