Abstract:
This study presents some results of turbulence studies in the flame and vicinity of the combustion source under model conditions for grassland and crown fires. These experiments were conducted between 2019 and 2025 at the IAO SB RAS BEC. Spectra of temperature changes in the flame and the atmosphere, turbulence scales in the flame, and scales of induced atmospheric turbulence in the vicinity of the combustion source are obtained. Graphs of changes in local atmospheric characteristics are presented.

Keywords:
turbulence, combustion, scale of turbulence
