Good morning Aamer.

It doesn't matter if the airfoil is moving or if it is static with wind blowning at the same velocity upon it. The same relative wind velocity is encountered for the airfoil...

Negative drag coefficient...

Greetings.

I'm trying to model a NACA 0006 airfoil to compare it experimental data (from Theory of Wing Sections, I. Abbott & V. Doenhoff). I'm trying to replicate in this case the flow for angle...
