In the present study, hydrodynamic journal bearings, considering the influence of surface roughness (SR), surface porosity (SP), and slip boundary condition (SBC), have been analyzed. To perform this investigation, a modified Reynolds equation with assuming Reynoldsboundary conditions has been solved. The Tripp model, Darcy law, and Modified Navier slip length model have been used to study the effect of SR, SP, and SBC. The variation of performance parameters such as lubricant pressure and lubricant film thickness with change in external applied load is investigated. It has been observed that, as compared to conventional bearing, bearing with SR, SP, and SBC shows significant improvement in the value of peak lubricant pressure and lubricant minimum film thickness.
