Temperature analysis of hydrodynamic journal bearing lubrication with a moving journal and a fixed bearing

The need for bearings in a variety of heavily loaded machines,
including the influence of pressure and temperature, is generating
increasing interest in studying the operating environment for
magazine bearings. The purpose of this work is to develop a semi-
analytical solution by introducing a new delta profile concept of the
location of zero velocity gradients to obtain the simplest form of
the equation of energy and Reynolds. In the journal bearing, assum
ing that journal is rotating and bearing is fixed, a hydrodynamic
lubrication is modelled with the Power Law fluid. The lubricant
temperature effect is examined under isothermal limits and the
results obtained are much more realistic with the experimental
results.
