reaction Rate
 

Hi;

I solved a combustion problem.My geometry was cylendrical. I used EBU-Arreius model that is minimum of ebu(eddy break up) and Arrenius model to calculate reaction rate . But in my postprocessing, temperature was almost everywhere low (between 400~500),whereas temperature should be greater than 2000.As soon as I used ebu(eddy break up) model , results tended to more logical temperetures. Nevertheless in literature it has been accepted EBU-Arrenius model , but in my code only EBU has logical results.Which model do you suggest?Why did it occur for my problem?

Thanks alot for any help.
