Abstract : This research program was conducted to determine the lubrication behavior of liquid metals. The objectives of the program were to study hydrodynamic bearing theory to determine the frictional characteristics, eccentricity, and load-carrying capacity of full journal bearings over a wide Sommerfeld number range and to compare experimental data with analytical data and attempt to explain any discrepancies. The hydrodynamic characteristics of a full journal bearing, four inches long with a L/D ratio of two and a 0.001 inch diametrical clearance, were determined with both Stoddard solvent and NaK 78 were used for lubrication. Data of frictional torque and eccentricity were obtained over a Sommerfeld number range of 0.7 to 3.0. The bearing load was constant at 160 lbs, and the speed range extended to 7500 rpm. The data resulting from both Stoddard solvent and NaK 78 are presented and the correlations revealed that they were in very close agreement with the predicted performance. (Author)
