Abstract:

We explored fire torch’s radiation in laboratory conditions. Fire torch was burning from a tank, which was fixed at the axis of uprising flow of air. Ethanol was used as a fuel. The description of processing of a thermogram sequence of the twisted torch is presented. The rotation frequency was determined by FFT conversion of time pulsation of thermovision signal.

Keywords:

thermovisor, vortex combustion, emission from a flame, frequency signal analysis
