  • 摘要: 可调谐二极管吸收光谱技术(tunable diode laser absorption spectroscopy,TDLAS)已成为超声速燃烧的重要测量手段之一. 为提高其空间分辨能力,需发展基于TDLAS,结合层析成像术的二维断层成像术(tunablediode laser absorption tomography, TDLAT). 设计了一套基于6 平行光束-旋转测量的新型TDLAT 系统,吸收波长为7 185.6 cm-1 和7 444.3 cm-1 双线,采用分时-直接吸收探测策略. 重建中,使用代数重建算法,先分别反演计算两吸收线的吸收率和吸收比分布,再获得温度和浓度分布. 利用该系统,在CH4/Air 预混平面燃烧炉上开展初步验证试验. 结果表明,TDLAT 系统可以反演出温度和浓度分布特征,反演的温度分布结果与热电偶测量值吻合较好. 进一步改进该系统,可用于超燃直连台中,测量燃烧室出口气流的温度和组分浓度分布.
