Abstract
Ferrofluid squeeze film in an axially undefined porous journal bearing was analyzed to determine its performance considering anisotropic permeability of the porous facing and slip velocity at the interface of porous matrix and film region using Jenkins flow model. Expressions were obtained for dimensionless pressure, load capacity and response time of the squeeze film. How to deduce results for no-slip case, isotropic porous case and for Neuringer–Rosensweig model case were indicated. The computed values of dimensionless load capacity and response time were displayed in graphical form. They increased with increasing values of eccentricity ratio and anisotropic parameter while they decreased with increasing values of slip parameter or material parameter of Jenkins model.
