Hello

I´m trying to make the validation for the sandi D Flame using EDC - reactingFoam. But my result are not very good. I have disabled the radiation properties then I change the meshing to have a more bigger computing space. like written in the Allrun file the simulation first make 1500 iteration without chemical then 10 000 iteration with kEpsilon turbulence modelling. Next I add 5 000 other iterations using realizableKE and my result seems unlogic.

I have two picture representing the contour plot of temperature and the axial plot of temperature with kEpsilon and realizableKE.

I think the result of kEpsilon is coherent but the one with reakizableKE seems to be quit bad. the gradient of temperature is very high after the maximum of temperature and I think it is not correct. But I cannot find the problem.


can you help me please ?
