Study of thermodynamic parameters and flame characteristics during wildfire using IR thermography

Abstract

The article presents results of experimental study of models of fire sources under semi-natural conditions. Experiments were conducted within the Basic Experimental Complex (BEC) of the Center for Collective Use “Atmosphere” of the Institute of Atmospheric Optics SB RAS. IR thermography was used to analyze the temperature field and its spectrum of changes at the fronts of steppe and crown fires. A narrow medium-wave IR range was used in this experiment. According to the results obtained, the temperature pulses at the fire front depend on the geometric position of the analyzed area relative to the entire combustion front.
