CFD Simulation of Methane Jet Burner

Methane jet flame simulations have been performed in order to evaluate conserved scalar chemistry (CSC) approach in modelling combustion process inside cylindrical burner. Two combustion regimes were included: non-premixed and premixed. For both of them it was necessary to generate look-up tables in pre-processing stage. For non-premixed regime two combustion controlling parameter approaches were used: scalar dissipation rate and normalized reaction progress variable (nRPV) approach. For premixed regime only nRPV approach was used. As an addition to CSC module, discrete transfer radiation module (DTRM) radiation model was also included. Simulation results were compared with experimental data.
