Abstract
Research about hydrodynamic thrust bearing always been developed, the most concern is case about texture with several configuration. Numerical approaches using Reynolds equations and CFD simulation based on Navier-Stokes equations are a common method that used to analyze bearing performance, but not all bearings can be examined by these two methods. Therefore, to find out parameter and boundary, it is necessary to analyze the effect of thrust bearing geometry by using Reynolds equation and Navier-Stokes equation. Single-textuerd thrust bearing with several geometry by certain reynolds number and cell aspect ratio was analyzed by CFD, and will be compared with the results based on the Reynolds equation. The result showed that the thrust bearing with proper cell aspect ratio and reynold number configuration could be analyzed using both methods, so we must configure velocity and use geometry correctly
