Author | A. Nessil, S. Larbi, H. Belhaneche |
The aim of this work is related to an analysis of
journal bearings lubrication, using non
Newtonian fluids, which are described by a
power-law model. The performance
characteristics are obtained for various values of
the non Newtonian power-law index ‘’n’’ that is
equal to: 0.9, 1 and 1.1. Numerical results
indicate that for dilatants fluids (n > 1), the
load-carrying capacity, the pressure, the
temperature, and the frictional force may be
greatly increased, while for the pseudo- plastic
fluids (n < 1), they all decrease. The thermal
effects are found to be more pronounced at
higher values of the flow behavior index ‘’n’’.
The results obtained in this study are compared
to those obtained by others. A good agreement
is observed between them.
