Title

RELATIVE STUDY OF A PLAIN CIRCULAR BEARING AND TWO-LOBE JOURNAL BEARING LUBRICATED WITH MICROPOLAR FLUID

Abstract

The consequence of the non-newtonian behaviour of micropolar lubricant for a plain circular bearing and two lobe journal bearing was in-vestigated and compared with Newtonian fluid. An empirical fluid flow equation which effectively represents the flow behaviour of lubricant was used to obtain a modified form of Reynolds’ equation. Finite difference numerical solutions were obtained for finite width bearing. The results show a strong influence on the load capacity of journal bearings by using micropolar lubricant for both the bearings. Linearized stiffness coefficients, damping coefficients, critical mass, and threshold speed and whirl frequency ratio for both the bearings for fixed eccentricity were evaluated. It is found from the study that the effect of micropolar parameter is very significant on the performance of journal bearing. The stability of both the bearings is improved while using micropolar fluid compared to Newtonian fluid.
