Paper VII(iii) A numerical solution of the elastohydrodynamic lubrication of elliptical contacts with thermal effects

Abstract

This paper describes a method for solving the problem of elastohydrodynamic lubrication in elliptical contacts which includes thermal effects. The technique is based on discrete formulations and computer solutions of the fluid flow. the solid elastic deflections and the heat transfer within both the fluid and the bounding solids. Detailed fluid pressure, film thickness and temperature solutions are reported for several conditions. The results clearly indicate the departure from isothermal conditions which exists as the entrainment velocity, and particularly the sliding velocity. are increased. The inclusion of thermal effects decreases the film thickness and the magnitude of the pressure spike by significant amounts
