Kameleon FireEx KFX
Kameleon FireEx KFX, often only referred to as KFX, is a commercial Computational Fluid Dynamics (CFD) program with main focus on gas dispersion and fire simulation. KFX uses the k-epsilon model for turbulence modelling, the Eddy Dissipation Concept (EDC) for combustion modelling, and a radiation model based on the Discrete Transfer Method (DTM) by Lockwood and Shah.
