20 February 2018 Non-uniform temperature measurement of flat flames using TDLAS
Author Affiliations +
Tunable Diode Laser Absorption Spectroscopy (TDLAS) is a non-intrusive method of measurement, which has lots of advantages, such as real-time, fast response, high sensitivity, easy operation, harsh condition applicability and so on. In this paper, the 7173.781201 and 7199.37761 cm-1 line pair of water vapor were selected for the temperature measurement of the flat flame burner. In order to observe the non-uniform temperature distribution, the Fourier-Hankel transform in the inverse Abel transform was used to convert the integrated temperature, which got by TDLAS, into temperature field.
