Analysis of 2D distribution of the frequency spectra of the flame model fire whirl

We investigated the fire whirl model obtained in a laboratory scale. The results of the IR camera application are presented. The spectral function of temporal fluctuations of the thermal imaging signal was calculated. We compared the spectral maximum with the rotational speed of the impeller. We have calculated the distribution of the spectral maxima in the flame of the fire whirl model. The probability of a correct determination of the rotation frequency of the torch from the spectral maximum depends essentially on the rotational speed.
