Validation of NACA 0012 against Nasa published;

Dear Fluent Users;

http://turbmodels.larc.nasa.gov/naca0012_val.html

Referring to this case I have shown link to I am sure every one has worked on it if you are interested in flow in aerospace.

I am having a tough time not knowing how NASA got their Reynolds number as 6 million.

The Reference Temp = 300K or 540 Rankine...
Flow M = 0.15 ~ is roughlu 51.45 m/s
Reference Chord Length = 1m;

Mu or Kinematic viscocity of air at 300k ~= 1.57e-05 m2/s.

And if so: Re = VL/(mu) = Therefore = (51.45 * 1)/(1.57e-05) = 3.28 million.

Can some one express their views

Regards

Shereez

Did you get an answer in the end?

I changed my kinematic viscosity in FLUENT to reach a Reynolds number of 6million - but I'm not sure if this is correct.
