Hydrodynamic Lubrication Theory Considering Electric Double Layer for Very Thin Water Film Lubrication of Ceramics.

Friction Control in Thin-Film Lubrication

A novel method is proposed for controlling and reducing friction in thin-film boundary lubricated junctions, through coupling of small amplitude (of the order of 1 Å) directional mechanical oscillations of the confining boundaries to the molecular degrees of freedom of the sheared interfacial lubricating fluid. Extensive grandcanonical molecular dynamics simulations revealed the nature of dynam...

Hydrodynamic Lubrication of Sliding Vanes

Hydrodynamic Lubrication of Rough Surfaces

Interacting surfaces are frequently found in mechanical systems and components. A lubricant is often added between the surfaces to separate them from mechanical contact in order to increase life and performance of the contacting surfaces. In this work various aspects of hydrodynamic lubrication are investigated theoretically. This is where interacting surfaces are completely separated by a flui...

Transition from Boundary Lubrication to Hydrodynamic Lubrication of Slider Bearings

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 spacing region from 0.125 to 0.25 pm. The ...
