J. Heat Transfer 139(7), 074505 (Apr 04, 2017) (5 pages) Paper No: HT-16-1235; doi: 10.1115/1.4036078 History: Received April 28, 2016; Revised January 24, 2017

A numerical thermal elastohydrodynamic lubrication (EHL) model is developed for coated line contacts by considering both the mechanical properties and the thermal properties of the coating and the substrate. The temperature fields within the oil film and within the solids are solved by deriving the energy equations for the solids and the oil film. Heat continuity conditions are satisfied at the interfaces between the solids and the oil film, and the coating/substrate interfaces. Effects of the slide-to-roll ratio (SR), the thermal conductivities of the coating bodies, and the oil film on temperature fields are studied.
