Lecture 11: Application case: airfoil broadband noise
Résumé
This lecture illustrates how the concepts developed along the previous lectures are applied to a popular subject of aeroacoustics: airfoil broadband noise. In particular the motivations for such investigations and the non-standard approaches used to tackle this topic are presented. In order to show a more detailed study than a general paper about airfoil aeroacoustics would allow, the scope is limited to the topic of tip leakage noise. Many of the experimental approaches shown here are also applicable or have been applied to other airfoil noise sources. However, a few ideas described hereafter have been specifically developed for the tip leakage study.
