Hi,
I'm trying to simulate an airfoil in Fluent, and I'm working with airfoils of the NACA 65 series, which are very thin.
The problem is that this airfoils become incredibly thin at 90% of the chord length or sooner ( < 0.8 mm of thickness), a geometry that would be impossible to fabricate.
I've been trying to engross the shape of the trailing edge, basically with a circunference of 2 mm diameter at it's end and connecting it with tangent arcs to the original airfoil. However, this aproximation is very poor since it would change the direction of the stream, and that's really important in my project.
I've included an ilustrative image.
¿Does someone know a better aproxximation to this problem?
Thank you!.
