Hi all,

I'm facing with the eternal problem of transport model...
I said "eternal" because before posting this thread, I was looking on many older posts which has been unsolved for years now.

Like most of the older post, I was initially looking for some As and Ts coefficient, in order to run reactingFoam (without reaction) using the Sutherland model (used in the counterFlowFlame2D OpenFOAM exemple).

The thing is:
  • As I said, it is very difficult to find liable values (even just values...)
  • This Transport properties model, based on modified Euken model seems not to be very accuracy.
So concretely, how do you prepare your Transport model for your simulation ?
  • Do you manage to find the Sutherland coefficient and temperature you need for your case ?
  • Do you use the polynomial model ? (but here again, there's the question on how to find the required coefficient... I can't see the light at the end of the tunnel)
  • Do you program your own Transport model ? (I'm freaking out, you're telling me that's how you do)
  • Do you simply use the const model whithout tempting to surch any coefficient... ? (I'm sure you worth better than this one)
Thank you for your replies,
Adrien
