Abstract

The study presents a steady state and transient solution for a finite width two – lobe bearing operating with a non – Newtonian lubricant, obeying the power – law model. A non – linear transient analysis is carried out and the orbital stability of journal is ensured by solving the equation of motion by fourth order Runge – Kutta method. Using the expressions for eccentricity ratio of lower and upper lobes and film thickness for each lobe, the modified Reynolds’ equation is solved separately for each lobe by finite difference technique with a successive over relaxation scheme. Performance parameters of two – lobe bearing like load carrying capacity, Sommerfeld number, attitude angle, flow and friction parameter are determined and compared with
