Type of article: Article

Summary

AN EXPERIMENTAL STUDY OF HEAT TRANSFER BY NATURAL CONVECTION OF HELIUM BETWEEN HORIZONTAL ISOTHERMAL CONCENTRIC CYLINDERS AT CRYOGENIC TEMPERATURES IS PERFORMED. OVERALL HEAT TRANSFER RATES, PROFILES OF THE TIME-AVERAGED TEMPERATURE, AND TEMPERATURE FLUCTUATIONS ARE MEASURED FOR RAYLEIGH NUMBERS OF 8 MILLIONS-2 MILLIARDS AND FOR EXPANSION NUMBERS OF 0. 25-1.0. AN EQUATION IS PRESENTED WHICH CORRELATES THE HEAT TRANSFER DATA BASED ON THE INNER-AND OUTER-CYLINDER DIAMETERS.
