abstract

  • © 1998 by AE. Morgan et al. We present the first experimental results of controlled radiative energy addition to a supersonic nozzle flow. In this experiment the output of a 10 kW cw CO2laser was absorbed by 250 ppm of Sulfur Hexaflouride (SF6) seeded into the Nitrogen flow. This first energy addition experiment is part of a larger test program aimed towards the development of a full scale radiatively driven hypersonic wind tunnel. The role of this experiment in the test program has been to serve as a proof of principle for radiative energy addition to a supersonic nozzle flow. The experimental design, results, and a comparison with numerical predictions are presented. Pressure and Mach number measurements clearly indicate that radiative energy addition produced a stable flow field. Measurements show qualitative agreement with numerical predictions.
