In this work, a numerical simulation for the thermo-hydrodynamic self-lubrication of
misaligned porous circular journal bearing has been investigated. Mathematical model
consists of a modified Reynolds equation to determine the pressure field of thin viscous oil
film taking into account the oil leakage into the porous matrix, Darcy’s law to determine the
fluid flow in the porous media and the energy and the heat conduction equations to
determine the temperature field in oil film thickness and the bearing shaft . The equation
used to evaluate the oil film thickness was modified to include the effect of the bearing
misalignment. The governing equations with appropriate boundary conditions were
simultaneously solved using finite difference approach.
