A finite element model is developed for parametric investigation of the influence of the rheological properties of the lubricant on the thermohydrodynamic film conditions which occur in a Rayleigh step bearing. The model is used to predict the thermohydrodynamic field in lubricating film with fixed geometry between the stationary and moving surfaces using power law fluids.
