A coupled finite-volume CFD solver for two-dimensional elasto-hydrodynamic lubrication problems with particular application to rolling element bearings [PDF]
This paper describes a new computational fluid dynamics methodology for modelling elastohydrodynamic contacts. A finite-volume technique is implemented in the ‘OpenFOAM’ package to solve the Navier-Stokes equations and resolve all gradients in a ...

Abstract Changes in the physical state of water may alter fault frictional properties in high‐temperature geothermal systems, yet they have been little studied. Here, we perform slide‐hold‐slide experiments to examine the frictional properties (frictional strength μss and frictional healing Δμ) of chlorite‐altered basalt from Krafla Geothermal Field ...

Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

RESEARCH ON DYNAMIC CHARACTERSITICS OF LINE CONTACT FRICTION PAIRS UNDER THERMAL EHL STATE
The line contact elasto-hydrodynamic lubrication (EHL) phenomenon generally exists in key parts of mechanical systems e. g. bearings, gears, the lubricant oil film between the contact interfaces acts as a spring and damper, and the frictional heat ...
