Combustion of gasoline-air mixtures in turbulent flow

Abstract

1. When the total turbulence of the isothermal incident flow and that generated by the flame are taken into account, the experimental data are quite close to the theoretical, thus confirming the physical concepts put forward by Damkahler and Shchelkin on flame transfer in turbulent flow by the flow pulsations and normal flame velocity. 2. The direct dependence of the turbulence generated by the flame on the normal combustion velocity increases the value of the latter in the transfer of flames in turbulent flow. 3. The turbulent flame propagation rate is determined by the maximum velocity of the flame seats relative to the fuel mixture. 4. The seats projecting towards the fresh fuel mixture form the foremost front of the flames and from these, as ignition sources, burn-up of the mixture proceeds in the combustion zone at the pulsation-bent flame surface.
