Non-Newtonian Thermal Elastohydrodynamic Lubrication

A numerical solution to the problem of thermal and non-Newtonian fluid model in elastohydrodynamic lubrication is presented. The generalized Reynolds equation was modified by the Eyring rheology model to incorporate the non-Newtonian effects of the fluid. The simultaneous system of modified Reynolds, elasticity and energy equations were numerically solved for the pressure, temperature and film thickness. Results have been presented for loads ranging from W = 7 × 10⁻⁵ to W = 2.3 × 10⁻⁴ and the speeds ranging from U* = 2 × 10⁻¹¹ to U* = 6 × 10⁻¹¹ at various slip conditions. Comparison between the isothermal and thermal non-Newtonian traction force has also been presented.
