Effect of Change in Radial Clearance on Pressure Variation of Fluid in Hydrodynamic Journal Bearing

Abstract

This
work entails the parametric study of the effect of the change in bearing radial
clearance with pressure variation of the fluid (lubricant) in a hydrodynamic journal
bearing was carried out. The classical Reynolds Equation was used to represent
the pressure behaviour in the bearing. This study was carried out using the
Galerkin Finite Element Method (GFEM). The result obtained shows that the
pressure increases from the ambient pressure which is taken to be zero and
increases significantly till 145.37370. At this point, the pressure
is maximum with 1.955 MPa and then drop until it gets to 1800 where
the pressure equals the ambient pressure. Between angular displacements of 1800
and 3600 there were also pressure variations which were equal in
magnitude with those between 00 and 3600 but with
different direction. From the foregoing, it is observed that as the radial
clearance increases, the pressure in the bearing drops significantly.
Therefore, in the design of journal bearings, the radial clearance should a
high as possible to reduce the pressure in the bearing. The result obtained
shows a strong positive correlation with existing result in literature.
