Abstract

We investigated the temporal fluctuations of the intensity of a laser beam through a vortex flame - a model of a fire tornado on a laboratory scale. Three equally spaced receivers were used. The spectral functions of fluctuations of the intensity of the laser beam were calculated at several speeds of swirling of the air flow incident on a stationary flame. Several spectral functions were recorded with a feature - a spike in the high-frequency region. Quantitative estimates of the shape of such spikes have been made.
