Coefficient of Drag
 

hi, I'm working at CFX and I got some problems with the coeficient of drag.
I`m using the k-e model of turbulance with intensity of 3,7%.
At the post, I got a plausible result of the Cl but de Cd is too high.
what i`m doing wrong?
i think that the mash is ok...

Cl and Cd
 

Hi P.C.!!

Im working on a clark y 3D wing for my dissertation. I have done a modified version of the clark Y and I would like to know how do get the coefficient of lift and drag.

Im a novice on ANSYS CFX, I have done all the meshing, setup and obtained results eventually for pressure, eddy viscosity and velocity contour.

Thank you for your consideration.
