Hydrodynamic journal bearing is a vital component in the rotating machinery since efficiency of the machine greatly depends on the performance of the bearing. The journal bearing performs well for medium speed, but at high speed fluid starts to whip around the journal due to which constant wedge shape is not form. Hence journal becomes unstable and starts vibrating. To avoid this for high speed hydrodynamic journal bearing, shape of inner diameter of the bearing is changed such that it will try to avoid oil whip. One of the such method is providing lobes on inner surface of the bearing. Two lobe and multi lobe (more than two lobe) are the two methods to provide lobe on the bearing. The present paper is the validation of the theoretical results obtained by them using Computational Fluid Dynamics (CFD) software package ANSYS 14.5. Also comparison of variation of pressure around bearing surface of Two Lobe and Simple Hydrodynamic Journal Bearing is compared.
