Experimental Investigation on Convective Heat Transfer in Annuli for Application to the Cooling of Reactors; CONTRIBUTION A L'ETUDE DE LA CONVECTION FORCEE DE LA CHALEUR DANS LES ESPACES ANNULAIRES EN VUE DE L'APPLICATION AU REFROIDISSEMENT DES CANAUX DE REACTEURS

Technical Report ·
OSTI ID:4265205

Convective heat transfer was investigated with two apparatuses of the same geometry, but in one case the wall temperature of the heated inner cylinder was constant and in the other case the heat flux was uniform. The local coeffifient of heat transfer in a partially developed flow was determined. Air at atmospheric pressure and temperature was used as the fluid, and the velocity varied from 0 to 120 m/sec. The method used for the measurement of the local coefficient of heat transfer is described. The effect of the geometry of the annuli, the effect of the air entry, and the distribution of the imposed flux were studied. (J.S.R.)
