Modification of the lubricated surface by combining the boundary slip and the texturing has proven to enhance the hydrodynamic performance of bearing. The present work explores the combined effect of boundary slip and texturing varying slip layout on the performance of journal bearing using computational fluid dynamic (CFD) approach. The effect of eccentricity ratio is also of particular interest. The results show that when the boundary slip is located on all edges of textured surface, more enhanced load support by 4% is obtained in comparison with classical (no-slip) textured one. However, in general the results also indicate that introducing the boundary slip with different layouts on partially textured surface does not much affect the hydrodynamic pressure as well as the load support; therefore, the slip-textured bearing shows similar and closer trend to the no-slip textured one. In addition, it is also found that the effect of eccentricity ratio is more influential than the boundary slip in terms of load support.
