Abstract

A numerical study of how mean flow around an airfoil affects acoustic shielding is presented. Many 2D simulations for a point source over a NACA0012 airfoil were conducted, where the source position and the mean flow are varied. Comparisons with wind tunnel tests prove the high quality of the numerical results. Based on the simulations the effect of boundary layers, wake and shear flow are investigated.
