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
