Eddy dissipation modeling of turbulent non-premixed combustion with radiation effect using openfoam

The Eddy dissipation model is one of the popular turbulent combustion models owing to its reasonable computational cost and accuracy. The purpose of this study is to implement the eddy dissipation model in OpenFOAM which is an open source code. It was implemented in many commercial CFD codes but it...
