New computational approaches are developed to explore ame stabi-
lization techniques in subsonic ramjets. The primary focus is statistical
modeling of turbulent combustion and derivation of the adequate bound-
ary conditions at open boundaries. The mechanism of ame stabilization
and blow-o in ramjet burners is discussed. The criterion of ame sta-
bility based on the clearly dened characteristic residence and reaction
times is suggested and validated by numerical simulations.
