Hello
The EDC turbulent combustion model is commonly used for diffusion flames in fires. The implementation in firFOAM confuses me since it differs from the literature. In the file fireFoam-2.2.x /thermophysicalModels/combustionModels/eddyDissipationModel/eddyDissipationModel.C the fuel reaction rate is coded as follows this->wFuel_ == this->rho() * min(YFuel, YO2/s.value()) / this->mesh_.time().deltaT() / Cstiff_ * (1 - exp(- Cstiff_*this->mesh_.time().deltaT() * rt)); Could anyone give comments on the extra term in bold? Is there any reference about this version of EDC combustion model? Thanks in advance!/Chen |
