Hi,

May I ask how to compute sutherland temperature? Shall I always use 110 K?

Thank you very much.

In my solver for air properties I use:

mu = C1*pow(T, 3/2)/(T+C2)
k = C3*pow(T, 3/2)/(T+C4)

where;

1.458e-06 !C1 - Sutherland's Law Dynamic Viscosity Constant
110.4 !C2 - Sutherland's Law Dynamic Viscosity Constant
2.495e-03 !C3 - Sutherland's Law Thermal Conductivity Constant
194.0 !C4 - Sutherland's Law Thermal Conductivity Constant

I am also curious if there are better values to be using based on the temperature ranges I am simulating...
