Hello.

I try to simulate combustion in a porous structure using eddy dissipation model. Convergence is okay, but the reaction rate is too small. The combusion should be (nearly) completed at the burner outlet, but the ch4 mass fraction is only half the inlet value. Is there a way to speed up the reaction?

THANK YOU A LOT IN ADVANCE!
