Abstract
The results of theoretical and experimental studies on determination of the scales of turbulent vortices in flame produced during the combustion of liquid hydrocarbon fuels and vegetable combustible materials with the usе of thermography methods are presented. A good agreement is shown between the sizes of temperature inhomogeneities experimentally measured in thermograms with the scales of turbulent vortices calculated from the spectra of the temperature variations in the test flame.
