  • Unstrained planar premixed flames (1D)

Freely propagating methane/air flame: ϕ = 1.0, T0 = 300 K, p0 = 1 atm. The flame is ignited by a heating source within the domain. The result has shown a good agreement with the computational data obtained with the commercial code Chemkin.

Harmonically excited plane-jet hydrogen/air flames with different frequencies and the same amplitude: ϕ = 0.5, unstable region with Le<1, Ma<0. The flame responds faster to the unsteady flow at low frequencies and tends to form instabilities at higher frequencies. At very high frequencies the flame's response is attenuated again.
