Abstract

Measuring the temperature field of the flame of a burning pyrotechnical composition from its infrared radiation is a difficult problem because of the high luminosity and high concentration of the condensed‐phase particles. In the present work, moire deflection tomography was used to measure the instantaneous temperature field during combustion of a pyrotechnical mixture. The boundaries of the burning region were clearly observed. The distribution of the refractive index of the axisymmetric burning region was reconstructed using numerical inversion of the Abel integral equation, and the temperature distribution in the horizontal section was obtained. The maximum value of the flame temperature was determined.
