On Thermal Reduction Factor for Elastohydrodynamic Film Thickness in Rolling/Sliding Contacts

This discussion on thermal effects in elastohydrodynamic films in rolling/sliding contacts is directed towards experimental validation of available analytical model for thermal reduction factor for elastohydrodynamic film thickness between two long steel cylinders against recently obtained experimental data with ball-on-a-disk-type test rigs. The discrepancy between the analytical predictions and experimental observations are correlated to the inconsistencies between model assumptions and experimental conditions.
