Abstract
The present study describes the theoretical investigation into the static and dynamic performance of a slot-entry hybrid journal bearing system by considering variation of viscosity due to temperature rise of the lubricant in the analysis. Required governing equations have been solved using the finite element method and a suitable iterative technique. Thermohydrostatic performance of a symmetric as well as asymmetric slot-entry hybrid journal bearing configuration have been studied vis-à-vis their isothermal performance. The results presented in the study indicate that the variation of viscosity due to temperature rise of the lubricant fluid-film affects the performance of slot-entry hybrid journal bearing systems quite appreciably.
