Abstract

In this work a numerical model to study axi-symmetric laminar diffusion flames has been developed based on the open-source CFD code OpenFOAM. The transport properties are calculated using a mixture-averaged approach, and thus the model takes into account the effects of differential diffusion for the gas-phase species. The flame solver showed good scalability up to 64 cores even for a moderately large chemical mechanism, and can be expected to scale even more strongly when larger chemical mechanisms are used. A semi-empirical two-equation soot model has been implemented and validated against experimental data for an ethylene flame. Radiative effects have been found to be significant in this flame configuration, and an optically thin model has been included to account for these effects. Initial results using these models have shown good agreement with experimental data and as a next step of this work, a detailed soot model, the Method of Moments with Interpolative Closure (MOMIC) has also been incorporated in the model.
