Sutherland coefficient of the species in a combustion -- CFD Online Discussion Forums

ErenC Member Eren Join Date: Aug 2018 Posts: 86 Rep Power: 9	Hello everyone! I am new to combustion and I am having hard time to understand "why all the Sutherland coefficients of the different species are the same" in tutorials. Even in GRI mechanism. I calculated Sutherland coefficients for 5 different species from a temp-visc measurement database and all the coefficients are different, but when I insert my own calculated coefficients combustion does not even start... I am thinking that these coefficients(in tutorials) are average coefficients of all species, but It doesn't make sense... I would be glad if someone can explain this. Thank you, Eren.
