Viscosity Change and its Effect on Pressure Distribution in Hydrodynamically Lubricated Journal Bearing

Abstract

In
this work, a parametric study of the change in lubricant viscosity with
pressure variation of fluid (lubricant) in a hydrodynamic journal bearing was
carried out. This study was carried out using the Finite Element Method (FEM)
and this was used to analyse the pressure behaviour of the bearing was
presented using the classical Reynolds Equation. From the result, it was
observed that at the beginning of the bearing where the pressure was equal to
the ambient pressure, the pressure increases thereafter till about 0.01875m where the pressure was at
maximum. From this point to the other trailing end of the bearing, the pressure
decreases to the ambient pressure at L =
0.025m
. At the early stage in the bearing, the pressure increase was seen
not to be that significant. This was usually between the ranges of 0 ≤ L ≤ 0.00625m. From this point
onward, the pressure begins to increase significantly. The reverse was the case
when the bearing’s angular displacement was in the range of 1800 ≤ L ≤ 3600.
The result also shows a linear relationship between viscosity and pressure. The
result obtained when compared with relevant literature shows a strong positive
agreement.
