Abstract

For the basic investigation of a premixed flame subjected to the effects of both flame stretch and flame curvature, the characteristics of the outward propagating cylindrical flame formed in an axially stretching flow were theoretically analyzed and compared with those of counter-flow twin flames, which have no curvature, and other types of non-stretched flames. The flame sheet model was first adopted for the parametrical investigation of the effects of Lewis number and preferential diffusion. Then, the finite reaction rate model was used and the extinction characteristics were analyzed over a wide range of equivalence ratios, resulting in the agreement of the extinction limit curves with the experimental data reported before.
