Paper Abstract

The flow field and fuel/air mixing patterns produced in an optically accessible, premixing/prevaporization section of a high pressure/high temperature combustor were examined via focused Schlieren high-speed photography. A focal plane, approximately 8 mm thick and centered within this section downstream of the fuel injectors, was imaged at a framing rate of 8,000 frames/second. High-speed focused Schlieren images were obtained for three different Venturi-type fuel injector configurations under identical experimental parameters. The results demonstrate the efficacy of this technique to discern fuel spray patternization, fuel-air mixing efficiencies, and mixing times of various fuel injector arrangements.
