The present work describes the performance characteristics of the capillary compensated symmetric and asymmetric hole-entry hybrid journal bearing systems considering the combined influence of the temperature rise and the non-Newtonian behaviour of the lubricant. The required governing equations have been solved using the finite-element method and a suitable iterative technique. The non-Newtonian lubricant has been assumed to follow the cubic shear stress law. The thermohydrostatic rheological performance of symmetric and asymmetric hole-entry hybrid journal bearing configurations is studied. The computed results show that the variation of viscosity due to the temperature rise and the non-Newtonian behaviour of the lubricant affects the performance of the hole-entry hybrid journal bearing system quite significantly.
