Calculation of the effective height of a diffusion flame

Experimental studies of coaxial burner flames make it possible to decide upon a Burke–Schumann model for “short” flames. Qualitative and scale conformity of diffusion flame shape is obtained for this solution. A satisfactory approximation of a flame by a plane model is given which considers changes in diffusion conditions in the gas phase and the mass combustion rate, and changes in the local ratios of the main ingredients of mixed solid fuels and their stoichiometric ratio.
