摘要：
The non-Newtonian temperature and pressure effects of graphite powder lubricant when added to a Newtonian carrier fluid and applied in a rotating hydrostatic step bearing is studied. Temperature and pressure profiles were determined both analytically and experimentally. Results revealed a temperature increase with bearing rotation speed for both fluids and compared favorably with the mathematical predictions. Experimental data also revealed a reduction in pressure at higher rotation speeds, a fact not demonstrated in the mathematical model.
