Problem 1

Consider the incompressible, inviscid airfoil calculation in FLUENT presented in class. Recall that the angle of attack, α, was 5°.

...

(b) Make a table of Cl and Cd values obtained for α = 0°, 5°, and 10°. Plot Cl vs.α for the three values of α. Make a linear least­squares fit of this data and obtain the slope. Compare your result to that obtained from inviscid, thin­airfoil theory:

where α is in degrees.
