| dc.description.abstract | This project investigates the
combination of upper surface dimples and trailing
edge serrations of a 3D thin airfoil and their effect
on aerodynamic performance. Dimples are known to
reduce a golf ball’s drag while a serrated trailing
edge is known to reduce noise. A flatback design is
also studied to see if its properties apply to a thin
airfoil. The airfoil in the present study is NREL S825,
to be 3D-printed with six combinations of the
proposed modifications and tested in a wind tunnel.
This study has found that the combination of
dimples, flatback, and serrations has increased the
maximum lift coefficient by 9.85%; however the
maximum lift-to-drag ratio has been reduced by
14.4%.
