Hi all,
Can anyone tell me how to simulate a swept back wing in 2d process? I found the geometry of swept back airfoil using matlab code,but found absurd result after simulation. The experimental data of naca shows the stall at 34 degree but i got the stall before 20 degree for the airfoil. Is it possible in this way? |

thanks. is it possible in fluent using 2d airfoil?

i'm sorry but i might have missed something. what exactly do you mean 2d swept back wing?
as for your last post, yes in fluent it is possible to simulate a 2d profile, but remember that the stall is extreamely hard to catch. EDIT: ok maybe i got it: you are talking about a profile deformed by the progection on the plane perpendicolar to the sweep. just remember that a 2d profile assume an inifinte aspect ratio and discrad the 3d effects, wich might be quite significative, both for performance and stall angle, on a real geometry. |
