Keywords: serrated trailing edge, noise reduction

This work presents an experimental study the effect of adding three different geometries of trailing-edge serrations, to a two-dimensional NACA 0012. The wing model has 92 pressure tapings for aerodynamic analisys which was complemented with trailing edge boundary layer measurements and wake mapping using hot wire measurements
