Thermal Design of a Radiant Gas Heater for Brayton Cycle Power System
Keyword(s):
The thermal design of a ground test gas heater for the NASA Brayton cycle power system is reviewed. The heater consists of a U-tube heat exchanger flowing a helium-xenon gas mixture, irradiated by a low-density pattern of tungsten filament quartz lamp heater modules, arranged to produce an exponential flux distribution along the tube axis. Choice of the correlating equation for gas-mixture forced-convection heat transfer, methods for selecting the most critical design cases with respect to flow friction and heat transfer, and the method of calculating radiant flux distribution for a particular heater module arrangement are discussed.
