The body-fitted grids were generated using a system of elliptical partial differential equations. The k-ε model was employed to describe the turbulent characteristics. EBU-Arrehenius turbulent combustion model was used to determine the chemical reaction rate, while a six-flux model was applied to predict heat radiation and its influence on the wall and gas temperature.
