Direct experimental determination of laminar flame speeds

摘要

The stability of premixed flames at ultralow strain ratesw was assessed experimentally and numericalloy in the stagnation flwo ocnfiguraiton,results indicate that there are inherent limitations in establishing weakly strained planar flames,and that th accuracy of the laminar flmae speeds obtiane through linear exrrapolations can,thus,be compromised.In view of these limitations,a new methodology is proposed for hte direct experimental detemrination of laminar flame speeds.
