drag coefficient
 
we are a group of italian students and we have some problems with 2d airfoil(Naca 63(2)215) in fluent.My Fluent results are not similar to experimental value.I refine the mesh with TGrid and we tryed all model of viscous. but in Report>Reference Value>area what do I write? Thank

Hi!

use the same area, that is used for the experimental values!

Re: drag coefficient
 
the reference area is used to compute the coefficients of lift and drag.for the airfoil consider a unit depth and the area will be 1*(chord).hence just give the value of the chord.
