摘要

Tunable Diode Laser Absorption Spectroscopy (TDLAS) is widely used for online and non-intrusive measurements of multiple parameters (temperature, species concentration and velocity) of hydrocarbon fuel combustion gas. Two crossed-beam scanned-wavelength Direct Absorption Spectroscopy (DAS) system with (7444.352+7444.371)/7185.597 cm-1 line-pair was developed for high-speed hydrocarbon fuel combustion gas measurement in Rocket Based Combined Cycle (RBCC). And it was applied to the online measurements in ground-test of RBCC. Temperature, H₂O concentration and velocity were obtained, and the relative deviation compared with CFD results was less than 12%. This work can provide important reference data for the combustion organization and structure optimization of RBCC.
