THERMAL ANALYSIS OF TWO LOBE NON-RECESSED HYBRID JOURNAL BEARINGS

Abstract

In this paper, an influence of thermal effect on the static and dynamic performance characteristics of capillary compensated two lobe non-recessed hybrid journal bearing systems is presented. The Reynolds equation, energy and conduction equations have been solved simultaneously to get its solution using finite element method and a suitable iterative scheme. The numerically simulated results for the symmetric bearing configuration have been presented for different values of offset factors. The numerically simulated results of the study indicate that the temperature rise considerably changes the performance of two lobe non-recessed journal bearing systems. A proper selection of bearing geometry may compensate the loss occurred due to temperature rise partially.
