COMBINED CONVECTION AND RADIATION IN RADIOISOTOPE THRUSTORS.

Abstract

Heat transfer by the combined effects of convection and radiation is investigated for radioisotope propulsion systems. Fully developed laminar flow is considered, with the transverse temperature profiles assumed to be the fully developed profiles for the local conditions. The governing equations are derived for non-insulated and insulated systems and the equations are solved numerically on an IBM 7094 computer. The assumptions used in the theoretical analysis are tested experimentally for the insulated case by simulating the radioisotope with a resistance heater and using hydrogen as a propellant. The theoretical and experimental data are compared for the range of flow rates tested. (Author)
