Abstract
This work evaluates texturing effects on the hydrodynamic behavior of journal bearings by analyzing the load carrying capacity and power loss. The classical Reynolds equation is considered as lubrication model and the Finite Volume Method (FVM) is used to evaluate the problem. A Full Multigrid (FMG) algorithm is employed to solve in a fast way these discrete equations. Partial and full texturing are studied, varying the operating conditions, and best textures parameters for each case are evaluated through Design of Experiments (DOE). Results show that power loss on journal bearing can be reduced with the proper choice of textures radius and maximum local depth, which strongly depends on operating conditions.
