Abstract : Acoustic vibrations or vibrations from a mechanical turbulizer imposed on a flame enables intensification of the gas combustion processes and regulation of the characteristics of the flame. However, at the present time there is no unified approach to the treatment of the physical principles of the effect of an acoustical field on a turbulent flame, and this can be explained basically by the limited amount of experimental data. The purpose of this article is to study the effect of acoustic vibrations on a bounded turbulent flame by analyzing concentration, temperature, velocity, and acoustic fields and the characteristics of turbulence within the volume of the furnace chamber. Studies were made under conditions close to the combustion of natural gas in industrial heat assemblies.
