Abstract

This study presents a thermohydrodynamic solution for a finite-width Journal bearing operating with non-Newtonian lubricants, obeying the power-law model. The steady-state characteristics are obtained by solving simultaneously the generalized Reynolds equation, energy equation and heat conduction equations in the bush and the shaft satisfying the proper boundary conditions. Heat transfer is assumed to be three dimensional in the fluid and the bush and two dimensional in the shaft. The generalized Reynolds equation and heat conduction equations are solved by finite difference technique with a successive over-relaxation scheme while the energy equation is solved by an implicit Richtmyer technique.The load carrying capacity of the bearing is compared with isothermal conditions assuming the the bush and the shaft are perfect conductors.
