Abstract
In this study, the microstructure of bearing surface is modeled as a thin porous film press-fitted on an impermeable surface. On the basis of the Brinkman-extended Darcy model with stress jump condition at the porous-media/fluid film interface, the effects of viscous shear stress and stress jump on the performance of finite journal bearings are examined. The Elrod algorithm as well as the successive over-relaxation method is utilized to solve the modified Reynolds equation and determine the accurate cavitation region. The results show that the increase in stress jump parameter (β) provides a decrease in the load capacity, an increase in the attitude angle, and an increase in the coefficient of friction.
