The dissertation report presents a theoretical analysis to investigate the influence of non-Newtonian pseudo-plastic and dilatant lubricant behaviour on 180 degree partial arc orifice compensated hydrostatic/hybrid journal bearings performance characteristics. An approximate solution for bearing performance characteristics has been computed from Reynolds’s equation using Finite Element Method technique, considering non-Newtonian power law model. The computed approximate solution shows that all the performance parameters such as minimum fluid film thickness, load carrying capacity, stiffness and damping of fluid etc. are affected by powerlaw index (n).
