Nucleate boiling heat transfer experiments were conducted using the flow stability loop. The test section and instrumentation were the same as used in previous forced convection experiments with this loop. The organic coolant, isopropyl diphenyl, was used. Results were compared with the nucleate boiling heat transfer model used in FUGUE, Levy's generalized boiling heat transfer equation. An experimental correlation coefficient, B/sub L/, was determined as a function of pressure. Excellent agreement was obtained between the experimental temperature differences and the values calculated with the Levy equation using the experimental correlation coefficient. The following ranges of variables were studied: heat flux, 40,000 to 100,000 Btu/hr ft/sup 2/; coolant velocity, 7 to 13 ft/sec; outlet pressure, 20 to 35 psia; wall superheat, 38 to 54 deg F; and coolant subcooling, 0 to 20 deg F. In all cases the experimental and calculated wall superheat temperatures agreed within 3 deg F. (auth)
