A coupled finite-volume CFD solver for two-dimensional elasto-hydrodynamic lubrication problems with particular application to rolling element bearings [PDF]

open access: yes, 2016
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 ...

Polymer Infiltration Into SURMOF Channels Enables Hydrophobic and Solid‐Like Slippery Functional Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

Flow of Lubricating Greases in Centralized Lubricating Systems

open access: yesBulletin of The Japan Petroleum Institute, 1968
This work was undertaken to determine the effects of the composition of lubricating greases on their flow behavior in centralized lubricating systems and to obtain criteria for the selection of suitable greases for these systems. Flow properties of several lubricating greases of various composition were measured by the ASTM apparent viscometer and a ...

Adaptive high-order finite element solution of transient elastohydrodynamic lubrication problems [PDF]

open access: yes, 2006
This article presents a new numerical method to solve transient line contact elastohydrodynamic lubrication (EHL) problems. A high-order discontinuous Galerkin (DG) finite element method is used for the spatial discretization, and the standard Crank ...

Parallel 3D Bioprinting on SLIPS‐Microarrays

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces the first truly parallel 3D bioprinting method, enabling both the simultaneous fabrication of hundreds of cell laden hydrogel 3D structures and their HTS in individual liquid compartments. By integrating Digital Light Processing (DLP) stereolithography with functional micropatterns, the platform decouples printing time from array ...

Soft lubrication: the elastohydrodynamics of non-conforming and conforming contacts

open access: yes, 2004
We study the lubrication of fluid-immersed soft interfaces and show that elastic deformation couples tangential and normal forces and thus generates lift. We consider materials that deform easily, due to either geometry (e.g.

Optimized design of the flow network in the lubrication system for the heavy vehicle transmission

open access: yes, 2017
An accurate simulation model of the lubrication system is essential for early design of the heavy truck transmission. In this article, a detailed computational method for the flow network analysis of the lubrication circuit is developed based on the ...

Multi‐Responsive Dendrimer‐Hyaluronic Acid Hydrogel With Lubricating and Immunoregulatory Functions for Synergistic Osteoarthritis Therapy

open access: yesAdvanced Functional Materials, EarlyView.
A hydrogel with dynamic cross‐links was formed by cross‐linking hyaluronic acid with curcumin‐preloaded, phenylboronic acid‐modified poly(amidoamine) dendrimers. This hydrogel exhibited excellent injectability and self‐healing ability, enabling controlled Cur release in response to low pH, high reactive oxygen species (ROS) generation, or mechanical ...
