The current work investigates the effect of wall-slip on the steady-state performance characteristics of three-lobe journal bearing operating with non-Newtonian lubricant. The power-law model is used to incorporate the non-Newtonian lubricant, while the Navier-slip boundary criteria is used to apply the wall-slip effect on sliding surfaces. Numerical simulations are performed employing the technique of finite difference to determine the performance characteristics under conditions of steady state. According to the findings of this study, it is revealed that the load-carrying capacity is increased by about 15.38% with a slip-length of B 1x = 0.2 when slip occurs on the wall of the journal surface.Keywords
