Abstract

It is shown that the well known difficulty concerning the unconditional stability of a planar flame sustained in a stagnation-point flow is due to the infinite aspect length scale of the system. In finite geometries occurring in numerical and laboratory experiments the flame may well become unstable provided the flow-induced stretch is weak enough.
