Hi everyone,

Concerning the reference values for a 3D simulation of an airfoil which have a symmetry wall in the middle: the "Reference Length" stays the same but the "Reference Area" should be doubled, right?

The aim is to calculate the cl and cd values.

Thanks for any help!

They're coefficients so will be the area in the model: total lift/drag would need to be doubled as you only have half of the wing.
