Abstract

Different versions of Perfectly Stirred Reactor (PSR) have been examined in the simulation of a methane-air jet flame, Sandia flame D. These models have been incorporated with a turbulent mixing based combustion model, Eddy Dissipation Concept (EDC), to address the interaction between turbulent flow field and chemical reactions. Turbulent small scale effects were modeled using Reynolds Average Navier Stokes (RANS) approach. A reduced chemical mechanism (DRM) was used in order to calculate the species reaction rates. Velocity profiles were in good agreement with experimental data. The modified model applied the effect of turbulent mixing by altering the PSR’ s species transport equation. Using the modified model resulted in an inevitable enhancement on the reactive scalar’ s distribution along the central axis. However the distribution of the scalar showed a slight over-prediction at the flame location, which was originated from using the reduced mechanism. The model capability in predicting the turbulent flame interaction was examined using a Computational Fluid Dynamic (CFD) toolbox, OpenFOAM.
