Abstract

Heat-transfer measurements have recently been completed while performing an experimental study of the operating conditions of a cryogenic heat pipe. These measurements have made it possible to determine condensing heat-transfer coefficients for nitrogen, hydrogen, and deuterium. The cryogenic heat pipe used in these studies consists of a boiler connected by a pipe to a condenser. Vapor and condensate flow in opposite directions in the pipe.
