Hi,

I want to reproduce the data from a AGARD-R-702 wind tunnel test around a NACA 64A010 airfoil with a static angle of attack of 4. Having a look at the given data I'm having problems to reproduce the exact test conditions, especially the total temperature. I'm using the data from table 2.17 which is:

M_inf = 0.789
p_inf = 134741 Pa
p_tot = 203169 Pa
Re = 12E6

Using Sutherlands Law for the viscosity of air I have three equations with three unknown (temperature, velocity and viscosity). Solving this equations I get the following results:

T_total = 329.27 K
U_inf = 270.63 m/s
mu_inf = 18E-6 Pa/s

Apart from being pretty high this temperature contradict the statement in the data table where the range of the tunnel temperature is given as 290K - 320 K. Anybody sees what the problem is?

Thanks in advance.
