Abstract: The present work is aimed to study the performance of a two lobe geometrically imperfect hybrid journal bearing system having different geometric shapes of recess. The finite element method has been used to numerically compute the performance characteristic parameters of a two lobe 4 pocket bearing system which include minimum fluid film thickness and fluid film stiffness coefficient. In the present work four different geometric shape of recess, i.e. circular, elliptical, square and triangular, and a geometrically imperfect journal, i.e. barrel shape journal have been analyzed. The comparative performance of all bearings has been made on the basis of the same bearing operating and geometric parameters for the same ratio of bearing to pocket area. The numerically simulated results indicate that an elliptical recessed shaped two lobe bearing provides the largest value of direct fluid film stiffness coefficient in vertical direction vis a vis other bearings studied in the present study.
