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 highfrequency region are determined.
