Supercritical Acoustic Flame Experiments

Abstract

This report documents a sequence of studies that were performed with a major objective to determine the combustion response of injectors with and without acoustic forcing. A previous project had focused primarily only on the fluid dynamics response without combustion. The experimental facility was extensively redesigned and reconstructed to allow combustion. The main type of injectors considered were shear coaxial injectors flowing liquid oxygen in the center jet and gaseous hydrogen in the annular jet. However an impinging element injector was also examined as was a gas centered swirl coaxial injector flowing gaseous oxygen in the center and swirling liquid kerosene. The project also received a tasking to investigate the effect of energetic additives on the combustion characteristics of single hydrocarbon fuel droplets as a different class of combustion response. The details of all these studies are extensively documented in the Appendix.
