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