Thermo-hydrodynamic analysis of the finite slider pad—Adiabatic conditions

Abstract

Results are presented of a three-dimensional analysis of the fluid film under a square fixed-geometry inclined slider pad. The analysis is applied to adiabatic conditions as a first step in the investigation of transverse viscosity gradient effects for a wide range of operating conditions. The predicted performance is compared with that obtained on the assumption of viscosity constant through the film thickness. The effect of the transverse viscosity variation is shown to reduce or enhance pressure generation according to the magnitude of two characteristic non-dimensional groups. The results are also compared with performance predicted on the basis of constant viscosity theory using an “effective” viscosity derived from an overall film energy balance.
