Abstract

The focus of this investigation is to study the effect of lubricant viscosity
variation on the performance of the finite width plain journal bearing with
Newtonian and non–Newtonian lubricans in the steady state operation.
Conventional and modified Reynolds equations in two dimensional forms
are solved numerically. The change in viscosity due to temperature
variation, using adiabatic solution, is taken into account.
The results of this work on Newtonian lubricant show that the viscosity
decreases under, at the same load parameter, and causes a decrease in the
shear force and an increase in the side leakage flow rate and eccentricity ratio.
For the non-Newtonian lubricant, at the same nonlinearity factor, the side
leakage flow rate increases due to viscosity variation, while the load capacity
and shear force are decreased.
