suggestion for thermophysicalproperties for high temperature buoyant flow
 
Hi,

I would like to run simple smoke distribution simulation in a ventilated compartement with some buoyant solver. I wonder, if you have a suggestion for the thermophysicalproperties. There is no combustion involved just volume sources for heat and smoke as a passive scalar (using swak4foam).

Up to now, I am using the standard:
thermoType hPsiThermo<pureMixture<constTransport<specieThermo <hConstThermo<perfectGas>>>>>;

mixture air 1 28.96 1004.4 0 1.831e-05 0.705;
pRef 100000;

but a better approach would probably be to use Sutherland law for viscosity... unfortunately I do not know, how I can get the values for As and Ts!? Maybe you have a suggestion for even other settings for this kind of pseudo-fire simulation... would be great!?

Best Regards!
Fabian
