Paper 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.
