- Abstract
- A thermal extinction model of two reactant, curved flames is presented using an asymptotic expansion with the reasonable condition of a large activation energy of the reaction rate. The perferential diffusions of the two reactants in the curved flames modify the thermal extinction condition of the flames. The extinction model was found to explain the characteristics in queching of cellular flames abserved in H2-O2-N2 flames.
