研究了一种可靠的、相对紧凑的、使用二极管激光双线原子荧光（TLAF）测量常压下反应流体温度的技术。使用铟和镓原子作为温度标记进行了TLAF温度测量，这是第一次。温度在多喷嘴燃烧器中测量，运行甲烷/空气火焰，提供从1600到2000 K的可变温度。在测量温度范围内，铟和镓的准确度相近，分别为2.7%和1%。通过在同一实验中同时进行旋转CARS测量，进一步验证了TLAF测温的可靠性。
A robust and relatively compact calibration-free thermometric technique using diode lasers two-line atomic fluorescence (TLAF) for reactive flows at atmospheric pressures is investigated. TLAF temperature measurements were conducted using indium and, for the first time, gallium atoms as temperature markers. The temperature was measured in a multi-jet burner running methane/ air flames providing variable temperatures ranging from 1600 to 2000 K. Indium and gallium were found to provide a similar accuracy of similar to 2.7% and precision of similar to 1% over the measured temperature range. The reliability of the TLAF thermometry was further tested by performing simultaneous rotational CARS measurements in the same experiments.
