Dear all

I am simulating a stator vane in cfx. I want to get drag coefficient for the blade so I used the force given by cfx-post and used the usual formula: force/(0.5*density*velocity^2*area)
I used the inlet conditions for density and velocity and I also used chord*span for the area. Have I used the right variables?
by doing this I obtained the drag coefficient of about 15. Isn't it too large? Shouldn't be always lower than unity?
Please tell me what is my problem? Is the area I am using ok?
for more information I should say my blade is a well-known c3x blade and it's setting angle is 59 degrees.

Thanks for your answers
