Remarks on thermal analyses of thin 4He films in superfluid heat pipe
Abstract
The heat-conduction equation on the thin films of superfluid is discussed with respect to entropy flows of the vapor and the thin film in heat pipe. Taking the approximation of the heat-conduction equation, it is shown that the thermal analyses based on the conventional theories depend only on the stationary state in thermal equilibrium. As a result, it is suggested tha some terms which include the entropy depending on temperature and the transient heat flow should be counted to contain the exact estimation on the output power of the heat flow in superfluid heat pipe.
