The combustion events in the swirl chamber and the main chamber are processed differently. The combustion in the swirl chamber is broken into three phases: low temperature ignition, high temperature premixed combustion and flamelet diffusion combustion, while the combustion in the main chamber is only considered as flamelet diffusion combustion. The Shell ignition model, global Arrhenius equation and coherent flamelet model are used to describe low temperature ignition kinetics, high temperature premixed kinetics combustion and flamelet diffusion combustion respectively.
