Abstract:

A study of pressure recovery in a supersonic flow in which energetic exothermic reactions occur has been performed that is applicable for a cw chemical laser. Analytical and experimental work has shown that typical HFDF laser flows can be recovered to approximately 200 Torr with the use of a constant-area diffuser. In addition, base relief, i.e., deadwater regions, in the laser nozzle can be used to facilitate constant-pressure operation in the laser cavity without significantly reducing the potential for pressure recovery in the diffuser.
