Stability of Premixed Laminar Flames in a Stagnation Point Flow to General Disturbances

Abstract

The researchers completed a stability analysis of the stagnation point flow to a general class of disturbances expressed an infinite series. They have shown that when truncated at some large N, a finite number of boundary value systems result for the determination of the growth rate and the flame shape that depends on N, on the cross stream wavenumber and on all the relevant physiochemical parameters. The stability results thus obtained reduce to those of Kim and Matalon (1990) when N=O and extend them to include corrugations in the direction of stretch with wave number proportional to N. The results are discussed in terms of the Lewis number which is related to the mixture composition, and the rate of strain experiences by the flame. This work was recently presented in the Fourth International Conference on Numerical Combustion held in St Petersburg, FL and has recently been published in Combustion Science Technology.
