“…In both cases, the steady-state solution remains unique and symmetric S ¼ 0 for all the mass fractions considered. A similar behavior has been reported before by Kurdyumov in [21], where very lean flames propagating in an adiabatic channel were studied.…”

“…For the reasons exposed above, we used the method developed by Kurdyumov in [21] to compute the eigenvalue with the largest real part. To study the emergence of the symmetric and asymmetric modes, we solved the above set of equations in the half-height domain 0 6 y 6 1=2 with boundary conditions…”

“…On the other hand, for Le F > 1, in cases where the planar flame suffers from oscillatory instabilities [12], the Poiseuille flow stabilises the flame and oscillatory solutions vanish. The effect of the differential diffusion between heat and mass in the symmetry-breaking or oscillatory instability occurrence is seen to decrease in importance as the width of the channel is reduced [6,7]. All the work cited above made use of the thermo-diffusive approximation, also called the constant density approximation, to eliminate the flame-fluid interaction due to thermal expansion and viscous effects and therefore to concentrate on the preferential diffusion effect of the fuel.…”

“…Although this simple kinetic model does not consider intermediate species, it has demonstrated an acceptable success in clarifying the role of the complex physical phenomena involved in flame dynamics in channels [4][5][6][7][8][9][10][11].…”
