Simplest combustion model

CFD Student

Dear CFD People,

I wrote density-based, Favre-Averaged Navier-Stokes solver based on 2-d finite volume cell-centered scheme with central averaging (JST) and upwind schemes (van leer, Roe FDS, E/H-CUSP) using dual time stepping method for simulating unsteady flows with Weiss&Smith preconditioner for computing flow in the incompressible limit. I also implemented Baldwin-Lomax and Spalart-Allmaras models for turbulence.

Although I am completely new in combustion modeling, I am willing to extend my code for simulating combustion and I want to start with the simplest model in 2-d. I heard "Arrhenius model" is the simplest one? is it true? Any help is greatly appreciated.

Best regards.

CFD Student.
