Abstract

This paper
presents numerical solution to the pressure distribution of a fluid in a
hydrodynamically lubricated journal bearing using the classical Reynolds
equation that models the effect of side or end leakage i.e., there is flow in
the z-direction in bearings. The finite element method was used to analyze the
flow. Two dimensional interpolation functions were used in the modelling and
discretization of the domain of analysis. The result obtained from this research shows that the pressure increases
from the ambient pressure which is taken to be zero at an angular displacement
of



















 and increases
significantly till

 . At this point, the
pressure becomes maximum. Thereafter, it begins to drop until it gets to

 where the pressure
becomes the same as the ambient pressure. From this point onward, we begin to
experience negative pressure. The negative pressures in this regard are those
that are below the ambient pressure.
