Lubrication of journal bearings: influence of stress jump condition at the porous-media/fluid film interface
TL;DR: In this article, the effects of viscous shear stress and stress jump on the performance of finite journal bearings were examined using the Brinkman-extended Darcy model with stress jump condition at the porous-media/fluid film interface.
Journal ArticleDOI
Hydrodynamic lubrication of finite porous journal bearings—Use of the Brinkman-extended Darcy model
Jaw-Ren Lin,Chi-Chuan Hwang +1 more
TL;DR: In this paper, the authors apply the Brinkman-extended Darcy model (BEDM) to investigate the hydrodynamic lubrication of finite porous journal bearings.
Journal ArticleDOI
Novel approach to solve the dynamical porous journal bearing problem
TL;DR: In this paper, a novel and fast approach to solve the dynamical porous journal bearing problem is proposed, which allows for the influence of rough surfaces on the hydrodynamic pressure implemented through flow-factors, journal misalignment and calculation of stiffness and damping coefficients for finite bearings.

Jaw-Ren Lin,Chi-Chuan Hwang +1 more
TL;DR: In this article, the weakly nonlinear stability characteristics of short porous journal-bearing systems are presented on the basis of the Brinkman model, by applying the Hopf bifurcation theory.

Modeling and simulation of porous journal bearings in multibody systems
TL;DR: This work is concerned with modeling porous journal bearings in multibody systems, for which dynamical models are needed to investigate the bearing’s behavior.
