| Outline of Final Research Achievements |
Spaceplane is a promising candidate for next generation space transportation system. Supersonic mixing and combustion are keys to realize the spaceplane. We developed a new technique to measure instantaneous injectant molar fraction in a supersonic flow through this project. The measurement technique is based on Planner Laser Induced Fluoresces (PLIF) using tracer molecules which are excited by laser light. To establish the technique, we first investigated photochemical characteristics of toluene under low-temperature and pressure conditions which is observed in a suction-type supersonic wind tunnel. Then, we established the two-color PLIF measurement system. By using this new measurement system, we are able to quantitatively evaluate mixing efficiency of fuel in a supersonic flow.
