Abstract

Abstract: 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.

摘要： 可调谐二极管激光器吸收光谱技术(Tunable Diode Laser Absorption Spectroscopy，TDLAS)广泛应用于碳氢燃料燃气参数(温度、组分浓度和气流速度)实时在线和非接触测量。针对碳氢燃料火箭基组合循环(Rocket Based Combined Cycle，RBCC)发动机的高速燃气参数测量，设计了双交叉光束(7444.352+7444.371)/7185.597cm-1谱线对扫描波长-时分复用双线直接吸收光谱技术(Direct Absorption Spectroscopy，DAS)系统，将其应用于RBCC地面实验高速燃气参数在线测量，同时获得了燃气温度、H2O组分浓度和速度等多参数，并将测量结果与数值模拟计算结果对比，相对偏差不超过12%，这为RBCC发动机燃烧组织优化和结构优化提供重要依据。
