Resumo

Sodium was condensed on the outside of a vertical, 1/2-inch diameter tube, internally cooled by a flow of liquid potassium at heat fluxes of from 215,000 to 583,000 BTU/hr.-sq.ft. The vapor temperature was varied from 1240°F to 1525°F providing a five-fold variation in the vapor density. The sodium condensing coefficient appeared to be constant at 10,800 ± 3300 BTU/hr.-sq.ft.-°F. This value agrees with previous data taken at much lower heat fluxes and represents 8 − 10 percent of the value predicted by Nusselt's theory.
