Abstract : The purpose of this research was to investigate the pressure and temperature effects of graphite powder lubricant added to a carrier fluid of ethylene glycol as applied in a rotating hydrostatic step bearing. After the testing apparatus was designed and modified, the temperature and pressure profiles were determined analytically and experimentally. The rheological behavior of the non-Newtonian lubricant was modeled using a Power Law model developed previously. This model has been proven to match experimental data and was therefore the tool used for comparison with research data. Ethylene glycol was used as the Newtonian lubricant for the initial experimentation, which provided a check on the test apparatus and a comparison with the non-Newtonian graphite slurry.
