reactingFoam - sutherland transport

DuarteMagalhaes · October 20, 2014, 13:56

Hi everyone,

I know there are a lot of posts on this subject, but still I couldn’t yet find an answer for it, and I am creating a new topic because I think there is still a large number of persons who are having this same problem.

I am using reactingFoam, OpenFOAM version 2.3.0, and using Sutherland's transport formula,

Can anyone tell me where I can find the As and Ts coefficients for O2, N2, H2O and CO2.

I have looked at the default thermo.compressibleGas file for counterFlowFlame2D tutorial but it presents the same equal coefficients for the different species, which is odd.

Thanks in advance!

Any news in 2016 Foamers ?

I have exactly the same question as DuarteMagalhaes... (instead I would like CH4 values too).

And have you any idea of the accuracy of this model ?
In which range of temperature should we use this model ?

Any help, any start of answer would be welcome
Thank you,
Adrien
