Investigation of optical inhomogeneities of a vortex flame

Abstract: On a laboratory scale, a vertical tornado-like flame with a height of up to 1 m and a diameter of the order of 0.05 m was investigated. A laser remote sensing of this flame at several altitudes was carried out. Fluctuations of the self-radiation of the flame in the visible range were recorded at these heights. We calculated the spectral functions of the intensity fluctuations for the probing laser beam and for the fluctuations of the self-radiation of the flame. For these spectral functions, the height dependences of the coordinates of the maxima and the coefficients of the tangent in the high-frequency region are determined.

Altitude dependence of intensity fluctuations of the laser beam crosses the rotating flame

Abstract: We investigated the vertical tornado flame obtained in a laboratory experiment. The results of laser sensing of the flame at several altitudes. Calculated spectral function of intensity fluctuations of a laser beam. For these functions are set depending altitude slopes in the high-frequency region.

Analysis: the intensity of fluctuations of a laser beam crossing a rotating flame

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.

Investigation of the 2D distribution of the spectra fluctuations of intensity of laser radiation sensing a swirling flame

Abstract: We conducted a study of the swirling flame with a laser. A vertical tornado-like flame had a height of approximately 1 m and a width of 0.07 m. At 10 heights for 3 equally spaced sensors with an ADC frequency of 100 kHz, signals of intensity fluctuations of the laser beam passing through the flame were recorded. Using the FFT, we calculated the pulsation spectra of the intensity of laser radiation. The 2D dependences of the parameters of the temporary spectral functions were obtained: the coordinates of the maxima and the tangent in the low frequency and two slopes in the high frequency range region are determined.
