Abstract

Planar imaging has been used in investigate flow mixing and soot formation under fuel rich combustion conditions. Cold flow measurements of the local mixture fraction distribution from a subscale, multi-element, liquid rocket gas generator injector have been made using an aerosol seeded oxidizer simulant. The mixture fraction distributions reveal that rapid mixing occurs near the face of the injector. Analysis of the stoichiometric mixture fraction contours indicate that the oxidizer jets may have short combustion lengths and resemble individual inverse diffusion flames. To examine the details of soot formation under these fuel rich conditions, an investigation of inverse diffusion flames using a uni-element, coaxial injector has been undertaken. Results from soot imaging measurements confirm the short flame lengths indicated by the cold flow measurements.
