A numerical design tool for textured hydrodynamic bearings
A numerical design tool for textured hydrodynamic bearings
A successful application of surface texturing in hydrodynamic bearings relies heavily on efficient numerical models. In this work, several ways to enhance the computational performance of models based on the Reynolds equation are presented and compared to conventional techniques. The present approach is based on a Finite Volume discretization of the Reynolds equation and takes into account mass-conserving cavitation as well as thermal effects. It is shown that applying special discretization schemes to handle discontinuities, using non-uniform and adaptive meshes, taking advantage of multicore processing and strategically utilising different algorithms to find the bearing equilibrium are ways to study textured bearings most efficiently. Furthermore, using the results of an equivalent untextured bearing as first approximation for the textured bearing is shown to significantly reduce computation times. Results are validated through CFD data and correlated with laboratory test results.

Abstract
A successful application of surface texturing in hydrodynamic bearings relies heavily on efficient numerical models. In this work, several ways to enhance the computational performance of models based on the Reynolds equation are presented and compared to conventional techniques. The present approach is based on a Finite Volume discretization of the Reynolds equation and takes into account mass-conserving cavitation as well as thermal effects. It is shown that applying special discretization schemes to handle discontinuities, using non-uniform and adaptive meshes, taking advantage of multicore processing and strategically utilising different algorithms to find the bearing equilibrium are ways to study textured bearings most efficiently. Furthermore, using the results of an equivalent untextured bearing as first approximation for the textured bearing is shown to significantly reduce computation times. Results are validated through CFD data and correlated with laboratory test results.
