EDCSMOKE: A NEW COMBUSTION SOLVER BASED ON OPENFOAM

A new OpenFOAM solver for combustion problems requiring detailed kinetic mechanisms is presented. The Eddy Dissipation Concept (EDC) is used as the turbulence-chemistry interaction model. The solver, called ”edcSimpleSMOKE” for the steady-state and ”edcPimpleSMOKE” for the unsteady form, was developed recently for a robust handling of large and detailed chemical mechanisms. The solver was validated using high-fidelity experimental data from several flames: the piloted methane-air Sandia flame D, the Sandia/ETHZurich CO/H2/N2 flames A & B, the DLR/TU/Sandia CH4/H2/N2 flame (DLR A), the Sandia/ETH H2/He flame and the Adelaide Jet in Hot Co-flow (JHC) flame. In general, satisfactory agreement is found between the simulations and the experimental results, for both temperature and species concentrations profiles. What’s more, a comparison is made between the different formulations of the EDC model.
