AIR molecular properties
 

What options for AIR molecular properties (i.e. density, Cv, conductivity) should I set for compressible flow?

Normally IDEAL GAS f(P,T) for density, constant specific heat capacity and conductivity are adequate. If temperature is high, you may also consider Suderland formula for laminar viscosity.

I obtain the temperature values x2 than they should be. What could be the reason? I have just 2 opposing inlets and pressure boundary (outlet, actually). The velocities are low. No chemistry. Do you have any ideas? (I hope you do :)

After I've set the 'Thermal' option for the enthalpy computation the temperature values are OK. But now there is no convergence after 1000 iterations (the enthalpy residual ~0.04).
