Hi all,

not sure if anyone can help me with this. I am trying to calculate the viscosity of air at high temperatures due to hypersonic speeds.

Is there any model or formulation available? i am looking at temperatures above 3000K, and probably where Sutherland's equation is not really valid anymore.

For temperatures below 10000K for calculating the properties of air, you can use programs using a model of thermodynamic equilibrium, eg CEA
