Abstract

Our previous experiments on burner-stabilized laminar premixed flames have identified four nonsteady modes of propagation:axial,radial,spiral and nonplanar.In this paper we present stability boundaries for the occurrence of these modes,at a fixed pressure,as a function of total flow rate and equivalence ratio.We also specify the character of one of the four modes,the nonplanar mode,in which the flame front vibrates like a circular drumhead.
