Transverse electrokinetic and microfluidic effects in micro-patterned channels: lubrication analysis for slab geometries

open access: yes, 2001
Off-diagonal (transverse) effects in micro-patterned geometries are predicted and analyzed within the general frame of linear response theory, relating applied presure gradient and electric field to flow and electric current.

Hydrodynamic Bearing Lubricated with Magnetic Fluids

open access: yesJournal of Intelligent Material Systems and Structures, 2009
This article summarizes the work carried out in the development of hydrodynamic lubricated journal bearings with magnetic fluids. Two different fluids have been analyzed: one is the ferrofluid from FERROTEC APG s10n and the other is the magnetorheological (MR) fluid from LORD Corp., MRF122-2ED.

Systematic Parameter Selection for Short Fiber Polymer Composite Direct Fiber Simulation

open access: yesPolymer Composites, Volume 47, Issue 7, Page 6319-6340, 10 April 2026.
Interactions of individually simulated fibers are systematically calibrated such that their orientation history agrees with the results from analytical orientation models. ABSTRACT The orientation of fibers in short discontinuous fiber reinforced polymer composites is a critical factor in determining final mechanical and thermal properties.

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

open access: yesAdvanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...

Analysis of Chaotic Features in Dry Gas Seal Friction State Using Acoustic Emission

open access: yesLubricants
In this study, a chaos theory-based characterization method is proposed to address the nonlinear behavior of acoustic emission (AE) signals during the startup and shutdown phases of dry gas seals. AE signals were collected through a controlled experiment

A Study on the Friction Reduction of Seal Ring for Automatic Transmission by Applying Surface Texture

open access: yesTribology Online, 2017
Texturing on sliding surface of resin seal ring was attempted to improve lubrication in this study. Numerical analysis of hydrodynamic flow at the sliding surface was conducted by Reynolds equation using the finite differential method.

Hydrodynamics determines collective motion and phase behavior of active colloids

open access: yes, 2013
We study the collective motion of confined spherical microswimmers such as active colloids which we model by so-called squirmers. To simulate hydrodynamic flow fields including thermal noise, we use the method of multi-particle collision dynamics.
