Hydrodynamic Bearing Lubricated with Magnetic Fluids
Journal 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.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...

Systematic Parameter Selection for Short Fiber Polymer Composite Direct Fiber Simulation
Polymer Composites, EarlyView.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.

Modeling Fiber Dispersion in a Single‐Screw Extruder for Long Fiber‐Reinforced Thermoplastics
Polymer Composites, EarlyView.Fiber dispersion throughout the screw channel ABSTRACT Understanding the mechanics of fiber attrition during the plasticizing process is important in predicting the strength of long fiber‐reinforced thermoplastics (LFT) composites. Fiber dispersion has been found to impact fiber damage during processing and therefore final fiber length in the final ...

Hydrodynamics determines collective motion and phase behavior of active colloids
, 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.

steel research international, EarlyView.This study investigates how drawing process parameters affect the tribological behavior of AISI 304 steel sheet. Under lubricated conditions, increasing normal force, drawing speed, and countersamples roughness reduces the coefficient of friction by up to 21%.

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