THE DEVELOPMENT OF A FOSSIL FUEL FIRED HEAT PIPE FOR USE WITH THERMIONIC ENERGY CONVERTERS.

Abstract

Work concerned the most efficient method of coupling a simulated thermionic converter to a heat pipe. The heat pipe incorporates a gas barrier and is used to conduct the heat from a fossil fuel burner to the simulated converter. A theoretical analysis of the operation of the heat pipe will be made and confirmed experimentally. Progress was made on the following tasks: the construction of a sodium heat pipe which operated to 1000 Centigrade; the evaluation of sodium as a working fluid; the evaluation of the wetting characteristics of lead on different capillary structures; the fabrication of vacuum tight ram seals and the development of a high strength alumina body for the barrier. Preliminary evaluations of the permeation characteristics of barrier materials was initiated. (Author)
