Contaminant Particle Motion in Lubricating Grease Flow: A Computational Fluid Dynamics Approach

Lubricants, 2018
In this paper, numerical simulations of particle migration in lubricating grease flow are presented. The rheology of three lithium greases with NLGI (National Lubricating Grease Institute) grades 00, 1 and 2 respectively are considered.

Microstructures, mechanical properties, and grease-lubricated sliding wear behavior of Cu-15Ni-8Sn-0.8Nb alloy with high strength and toughness

Friction, 2020
Alloys used as bearings in aircraft landing gear are required to reduce friction and wear as well as improve the load-carrying capability due to the increased aircraft weights. Cu-15Ni-8Sn-0.8Nb alloy is well known for possessing good mechanical and wear

Effect of UHMWPE Incorporation on the Tribological Performance of Carbon fiber‐Reinforced PEEK Nanocomposites

Journal of Applied Polymer Science, EarlyView.
UHMWPE provides interfacial lubrication, improving tribological performance of PEEK‐based sliding bearing bushings. ABSTRACT Ultra‐high molecular weight polyethylene (UHMWPE) was incorporated into a PEEK‐based hybrid material as a lubrication additive to improve the friction and wear performance of the composite due to its superior lubricity ...

EFFECT OF POLYMERIC POWDER ON THE FRICTION AND WEAR OF SAND CONTAMINATED GREASED SURFACES [PDF]

Journal of the Egyptian Society of Tribology, 2010
The present work aims to develop the abrasion resistance of surfaces lubricated by contaminated greases. The intended development can be achieved by reducing the effect of abrasive action of sand particles on the wear of the friction surfaces.

Dissecting the dissection laboratory: Elements for designing a human anatomy laboratory

Anatomical Sciences Education, EarlyView.
Abstract The human anatomy dissection laboratory is a critical component of anatomical and medical education. Development, maintenance, and stocking of these laboratory spaces have unique demands, with all of the challenges in running a laboratory with Biosafety Laboratory Level 2 (BSL‐2) classification, housing a large volume of tissues saturated with

Relationship Between Micro‐Level Circular Economy and Sustainable Performance in the Metalworking Industry

Sustainable Development, EarlyView.
ABSTRACT The large multinational metalworking industry has increasingly adopted micro‐level circular economy (MLCE) practices; however, the extent to which these initiatives translate into sustainable performance remains insufficiently understood. This study examines the relationship between MLCE and economic, environmental, and social performance ...

Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

Wind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one
