Research Abstract

Evolution of flame instability of premixed flame with a given initial curvature by external laser irradiation method was investigated. At first the method was applied to open flat flame burner and the effect of Lewis number (Le) on the growth rate of curved flame was experimentally revealed. The growth rate was apparently larger with lower Le. In experiments with propagation tube, the interaction between acoustic field and curved flame was investigated. As a result of the investigation, non-dimensional number, Pulsating Froude Number, Gp, was newly defined in the present work and it was concluded that the criterion of self-turbulization in acoustic field could be given by the non-dimensional number.
