- This paper presents significantly improved predictions for elastohydrodynamic (EHD) point contacts. Interferometric studies of such contacts show a keyhole-shaped conjunction with side leakage flow through contact side lobes. Previous predictions failed to exhibit this feature as they used idealised boundary conditions. The authors measured contact pressures using a method originally developed under Ministry of Defence funding. Novel boundary conditions, conforming with interferometric observations, were thereby developed for inlet flow and outlet cavitation wake. This approach enhanced EHD predictions, demonstrating that traditional analyses under-estimate friction by up to 20%. This is important because EHD conditions affect 90% of all machine elements.
