Flame extinction by periodic flow field. (English) Zbl 0717.76108

Summary: It is shown that the adiabatic premixed flame propagating through zero- mean, time-independent, periodic flow-field is quenched provided the flow-field intensity exceeds a certain critical level. It is argued that this effect may be relevant to the experimentally known phenomenon of flame quenching by turbulence.
