non-adiabatic, flame speed, combustion waves, competitive exothermic-endothemic


We numerically derive the properties of reaction fronts arising in a pre-mixed one dimensional two staged non-adiabatic competitive exothermic-endothermic reaction scheme where both reaction pathways compete for the same fuel. We utilise FlexPDE and the method of lines to obtain numerical solutions for properties such as the front speed and stability over a range of parameter values such as the Lewis number and the ratios of enthalpies and activation energies. Steady and pulsating speeds are demonstrated for specific regions of the parameter space. We also show that in some circumstances there exists a chaotic regime of combustion wave propagation.
