Since the lift and drag coefficient also depends on the Mach number beisdes Re number, I'd like to know which page of this book tells the Mach number in its experiment for NACA 2412. I looked for...

This will be really helpful. Btw, my simulation will be more around Ma=0.15 which is much lower than this test case. Could I still use this test data for the CFD validation for...

So people do 2D validation to feel a little more comfortable about the 3D prediction results? And where to find the 3D experimental data to have a clue about how far is 3D CFD from experiment?

But does the book 'Theory of Wing Sections: Including a Summary of Airfoil Data (Dover Books on Aeronautical Engineering)' also include 3D data? I thought it only has 2D airfoil data. I know how...

But 2D and 3D are very different things. The resolve of the secondary flow needs also to be validated. Otherwise how could induced drag prediction be validated?

Replies: 18 Looking for 3D wind tunnel airfoil(wing) experimental data for CFD validation Views: 5,593 Posted By Anna Tian Looking for 3D wind tunnel airfoil(wing) experimental data for CFD validation Hi, Currently I need to model the 3D wing for lift and drag coefficient calculations. I need some 3D wind tunnel experimental data for the CFD validation so that I can feel more comfortable about...
