FLUID-FLOW AND THERMAL-ANALYSIS OF A CIRCULAR JOURNAL BEARING

In this paper, three dimensional momentum and continuity equations and three dimensional energy equations are solved simultaneously to obtai n pressure, velocity and temperature field in the fluid of a hydrodyna mic circular journal bearing. Solutions of these equations are obtaine d by using the powerful numerical technique, finite element method. Fo r a range of values of eccentricity ratios, the static performance cha racteristics in terms of the load capacity, attitude angle, end leakag e and the power loss are computed and the results are presented.
