Influence of external magnetic field on the tribological performance of magnetic fluids in different lubrication regimes

Friction
Magnetic fluids (MFs) represent a unique class of smart functional lubricating materials, with their physical properties tunable by the application of a magnetic field.

Boundary lubrication properties of materials with expansive freezing

, 2002
We have performed molecular dynamics simulations of solid-solid contacts lubricated by a model fluid displaying many of the properties of water, particularly its expansive freezing.

Running-in wear modeling of honed surface for combustion engine cylinder liners [PDF]

, 2013
The texture change during running-in alters the performance and efficiency of a tribo-mechanical system. During mass production of cylinder liners, a final finishing stage known as ‘‘plateau honing’’ is commonly added to reduce the running-in wear ...

Boundary mode frictional properties of engineered cartilaginous tissues [PDF]

European Cells & Materials, 2007
Despite the fact that lubrication is a primary function of articular cartilage, there is little information on the frictional properties of cartilaginous engineered tissues.

Identifying the optimal interfacial parameter correlated with hydrodynamic lubrication

Friction, 2016
The effects of boundary (liquid/solid) slip on hydrodynamics are well recognized. However, it is extremely difficult to quantify in-situ boundary slip in a lubrication contact.

The non-Newtonian rheology of dilute colloidal suspensions [PDF]

, 2002
The non-Newtonian rheology is calculated numerically to second order in the volume fraction in steady simple shear flows for Brownian hard spheres in the presence of hydrodynamic and excluded volume interactions. Previous analytical and numerical results

Study on Atomization Mechanism of Oil Injection Lubrication for Rolling Bearing Based on Stratified Method

Lubricants
The atomization mechanism of lubrication fluid in rolling bearings under high-speed airflow between the rings was investigated. A simulation model of gas–liquid two-phase flow in angular contact ball bearings was developed, and the jet lubrication ...

Experimental and Theoretical Investigation for Shaft Journal Bearing Lubrication Performance [PDF]

Port Said Engineering Research Journal
Hydrodynamic lubrication is definitely one of the foremost factors upon which the load carrying capacity within journal bearing mainly rely. Therefore, maintaining journal bearing lubrication away from boundary and transient lubrication regions is so ...

Sedimentation and Flow Through Porous Media: Simulating Dynamically Coupled Discrete and Continuum Phases [PDF]

, 1995
We describe a method to address efficiently problems of two-phase flow in the regime of low particle Reynolds number and negligible Brownian motion. One of the phases is an incompressible continuous fluid and the other a discrete particulate phase which ...

Propulsion Mechanisms for Leidenfrost Solids on Ratchets [PDF]

, 2013
We propose a model for the propulsion of Leidenfrost solids on ratchets based on viscous drag due to the flow of evaporating vapor. The model assumes pressure-driven flow described by the Navier-Stokes equations and is mainly studied in lubrication ...
