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, assuming 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.
