Abstract

This theoretical investigation has been performed to explore the dynamic performance characteristics of micropolar lubricated porous hydrodynamic journal bearing considering slip effect along tangential direction. The properties of finite porous hydrodynamic journal bearings and micropolar lubricant and the Beavers-Joseph slip model are combined to reestablish the modified Reynolds equation. Dynamic nature of the bearing can be obtained by implementation of the first order perturbation technique in bearing properties. This research work on micropolar lubricated porous hydrodynamic journal bearing in dynamic condition has produced superior linear stability as compared to lubrication using Newtonian fluid.
