Abstract

The numerical modelling of thermal effects in elastohydrodynamic lubrication solvers is addressed by extending the code of the authors. This code is used to investigate the important effect of shear upon the temperature profiles for both a steady state and a transient line reversal example and also for a steady state point contact problem. Additional equations for the modelling of mean and surface temperatures within an elastohydrodynamic lubrication contact are described and are added into the existing multigrid driven solver. Temperature profiles in steady line and point contact cases are presented and used to demonstrate that even small amounts of shear produce temperatures in excess of those in the pure rolling case.
