Abstract

An equation is derived which describes the evolution of a corrugated flame front stabilized in stagnation-point flow: Φ_τ+4Δ⁴Φ+Δ²Φ+1/2(ΔΦ)²+α(ηΦ)_η=0 It is shown that, if blowing is sufficiently strong, the corrugations disappear and a plane flame results. The problem turns out to be rather unusual in the sense that the phenomena cannot be fully described by means of the classical linear stability analysis.
