Hi there,

I'm fairly new to fluent so bear with me.

Let me explain my situation:

I am doing a 2D simulation of airfoils (to be more specific NACA 4421 and NACA 23012) and I am confused with what the Cd and Cl are in terms of. Is the Cd and Cl displayed while the simulation is running in units of per meter?

Also, what should my reference area be? My chord length is 2, however, there are alot of opinions that say that the reference area should be the chord length, others that say that it should be the chord length squared.

If you could give any input, that would be great!

Thanks,

sniperees.
