Abstract

The effect of the non-Newtonian behaviour of lubricants, resulting from the addition of polymers, on the performance of hydrodynamic journal bearings is investigated. The model of non-Newtonian lubricant developed by Dien and Elrod is taken into consideration. An attempt has been made to evaluate the mass parameter (a measure of stability) besides finding out the steady-state characteristics of finite journal bearings with non-Newtonian lubricants. A non-linear time transient analysis is carried out for the stability analysis.
