Numerical study of supersonic turbulent combustion by flamelet/progress variable model

This paper conducts a numerical simulation of the well-known Burrows–Kurkov supersonic reacting wall-jet experiment based on the framework of Reynolds-averaged Navier-Stokes (RANS). Three kinds of turbulent combustion model including steady flamelet model with compressible correction (SF), representative interactive flamelet model (RIF) and flamelet/progress variable model with compressible correction (FPV) are adopted and compared with each other. The simulation results show that, the FPV model can capture the auto-ignition position correctly, whereas the SF model and RIF model predict a much earlier auto-ignition position. The FPV model shows better performance than the SF model and RIF model in the prediction of the temperature and species mass fraction distribution at the exit plane of the combustor. Particularly, the simulation of the experiment based on the RIF model and FPV model is the first time according to the literature research of the authors.
