dear all!

i implemented the eddy dissipation concept combustion model with infinitely fast chemistry according to the paper of Magnussen: "The Eddy Dissipation Concept A Bridge Between Science And Technology", Lisbon, 2005, based on fireFoam, using a k-eps turbulence model. the code runs and the flow field looks plausible at first sight (in 3D). but when integrating the reaction rate (or the heat release due to burnt fuel) over the whole computational domain, I can see that the reaction rate is overestimated, i.e. more fuel burns as is injected. I tried to increase spatial resolution as well as to change the value for the turbulent dissipation rate at fuel inlet but always observe the same behavior. Interestingly the reaction rate matches quiet well with the injected amount of fuel for the 2D tutorial case applying k-eps turbulence model.

Anybody experienced similar problems??

I would greatly appreciate your comments!!
