Summary

AN EXPERIMENTAL STUDY OF FREE CONVECTION HEAT TRANSFER FROM A COPPER SPHERE TO SUPERCRITICAL HELIUM IS PRESENTED. THE HEAT-TRANSFER COEFFICIENT IS MEASURED IN THE TRANSPOSED CRITICAL LINE REGION COVERING PRESSURES FROM 2.3 -35 ATM (0.23 -3.55 MPA) AND TEMPERATURES FROM 5.3 AND 25 K. A BOILING-LIKE PHENOMENON IS OBSERVED EXPERIMENTALLY NEAR THE CRITICAL POINT IN THAT THE HEAT-TRANSFER COEFFICIENT INCREASES WITH TEMPERATURE DIFFERENCE UNTIL IT REACHES A MAXIMUM.
