Abstract

Numerous published studies on the non-wettable surfaces with surface texture and slip conditions have been reviewed comprehensively to evaluate the performance of hydrodynamic bearings from last two decades. The recent numerical and experimental studies have been explored to observe the individual and combined influence of surface texture and slip. A variety of texture shapes and optimized slip zone profiles have also been discussed in this article. It has been observed from the literature that a suitable combination of modified slip and the conventional no-slip zone is effective in improving dynamic and static performance of hydrodynamic bearings. Many experimental studies also revealed that micro-scale textures are significantly capable of improving the tribological performance. Moreover, slip boundary condition is more beneficial at low and medium eccentricity ratios.
