EXPERIMENTAL AND NUMERICAL STUDY OF TEMPERATURE FIELDS AND FLOWS IN FLAME DURING THE DIFFUSION COMBUSTION OF CERTAIN LIQUID FUELS

摘要

The paper represents experimental studying the pulsations of temperature fields and the structure of a flow in the flame formed during the combustion of certain fuels. Also, the paper provides the mathematical modeling of a flow in the flame formed during the combustion of diesel fuels, as well as the comparison with experimental data and the estimation of the scale for turbulent vortices in flame. The experimental results are in satisfactory agreement with numerical modeling, which confirms the hypothesis of similarity for the pulsations of hydrodynamic and thermodynamic parameters.
