Modelling of Low-Mach Number Gas Flame Propagation

A new model and a new numerical method are applied to the simulation of the transient of a flame in a BurkeSchumann conguration all through the steady state for dierent ignition conditions The model built to simulate unsteady reacting flows at low Mach number is tested against this transient flame propagation in which strong property variations take place The results illustrate the interactions between the combustion reaction and the fluid dynamics
