摘要: Abstract Now-a-days a lot of thrust is given on the research related to geometrical modifications hydrodynamic lubricated bearing systems. Introducing deterministic micro-textures journal surface considered be one key approaches for improving performance. In this paper, performance analysis done without considering effect cavitation study different triangular, circular and rectangular micro-textured grooves ribs surfaces using COMSOL Multiphysics software. Initially, static carried out system with smooth thin fluid film method results same are validated analytical results. later part numerical surfaces. The simulation these studies shows that value maximum pressure frictional power loss significantly affected by introduction micro-textures. Bearing resulted in development losses as compared other Similarly micro-texture gave minimum
