Hypersonic flow
 
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.

Thanks!

For temperatures below 10000K for calculating the properties of air, you can use programs using a model of thermodynamic equilibrium, eg CEA http://cearun.grc.nasa.gov/
