Abstract

On a laboratory scale, a tornado-like flame was obtained. To study the optical inhomogeneities of such a flame, the laser transmission method was used. On different heights for 3 equally spaced horizontal sensors were digitized and signals of fluctuations in the intensity of the laser beam were recorded. When processed using FFT, the frequency spectra of intensity fluctuations were obtained. In the analysis of the spectra, sometimes occurring high-frequency peaks were distinguished. The distribution of such peaks was recorded depending on the recording time for each of the sensors.
