Abstract

Cavity is a promising flame-holding scheme that is widely studied for Scramjet combustor. Rear-wall-expansion cavity flow combines the characteristics of backward facing step and wall cavity. The turbulent mixing of the transverse jet and the cavity flow was computationally studied using the large-eddy simulation (LES) and the chemical reaction was modelled using the eddy dissipation model (EDM) and the flamelet model (FM). The effects of different combustion models in the methane fueled combustor were discussed. The characteristics of the flame stabilization and flame temperature demonstrated that FM is a promising combustion model. EDM captured sufficient information of the flame stabilization under a highly turbulent region, such as cavity etc.
