Abstract

Analysis of non-porous and partial porous layered regions on the bearing surface using ferrofluid lubrication is presented. Modified Brinkman model is used in the analysis of fluid flow in the partial porous region. Displaced infinitely long wire magnetic field model is applied for Ferrofluid lubricated journal bearing analysis. Non-dimensional load capacity and coefficient of friction are evaluated under the influence of extent of non-porous film region, permeability of porous media, porous layer thickness, magnetic field intensity and distance ratio parameter. A partial porous layered journal bearing lubricated with ferrofluid increases the load carrying capacity and reduces the coefficient of friction.
