Multiplicity and stability of the hydrogen‐oxygen‐nitrogen flame: The influence of chemical pathways and kinetics on transitions between steady states

Abstract

Abstract Numerical bifurcation techniques are used to predict multiple steady states for a nonadiabatic, premixed hydrogen flame stabilized on a flat‐flame burner. It is found that predicted conditions for burnout and ignition vary remarkably as rival chemical niodels are selected, while conditions for a well‐stabilized flame are much less sensitive to chemical and kinetic assumptions. It is concluded that multiplicity theory can help define the chemical behavior of realistic, complex reaction‐diffusion systems.
