Kurzfassung
In a two-step CFD-CAA simulation framework with DLR's CAA code PIANO enhanced by the treatment for porous materials simulations of a NACA0012 airfoil with a trailing edge made of porous materials starting at 88.75% chord length were run. The beneficial influence of porous materials was shown to be in good accordance with the experimental results. Furthermore, the effect of anisotropic as well as non-uniform materials was studied. Particularly, it was found that the application of nonuniform materials, as shown in Fig. 31, yields a notable noise reduction potential.
