Abstract

The effect of gas-phase and surface radiation on the structure and extinction of a diffusion flame stabilized on a condensed fuel has been analyzed using a matched asymptotic expansion technique by adopting stagnation-point flow as the model problem. An assumption of an optically thin limit in the gas phase is applied in the analysis. Results show that extinction is caused by the surface radiation loss from a condensed fuel in the small-stretch regime while gas-phase radiation has a significant effect in the high-stretch regime. The dominant extinction mechanisms for a diffusion flame on a condensed fuel is found to be fuel leakage in the high-stretch regime and both fuel and oxidizer leakage in the small-stretch regime.
