The effects of non-Newtonian lubricant behavior are investigated numerically for elliptically shaped journal bearings subjected to transient loads. The analysis is based on the mass-conserving finite element cavitation model of Kumar and Booker. The results reveal that non-Newtonian effects have an important influence on journal bearing performance. It is found that there is a significant increase in the maximum film pressure and flow rate whereas a significant decrease in the minimum film thickness and power loss.
