Aeroacoustic wind tunnel tests are a fundamental tool for fundamental aeroacoustic studies of single and multi-element airfoils. Hard-wall, open-jet, and hybrid wind tunnel test section types can nowadays be used for these type of studies. These test

Surface roughness elements are commonly used in wind tunnel testing to hasten the laminar-turbulent transition of the boundary layer in model tests to mimic the aerodynamic effects present in the full-scale application. These devices can alter the ch

We experimentally investigate the comparability of airfoil trailing-edge noise measurements in an open-jet, hard-wall and hybrid test section wind tunnel in a set of benchmark exercises. We used three different airfoils, namely a NACA-0012, NACA-0018

Acoustic imaging methods like beamforming rely on the propagation delay between source and observer. For open jet measurements the propagation delay is computed by a method proposed by Amiet, which has been used successfully for acoustic wind tunnels

Human factors, specifically visual impact and noise production, are the current main limitations for broader urban wind energy exploitation. Trailing edge noise, caused by the turbulent boundary layer interacting with the airfoil surface, is the prim

Small-scale wind tunnel tests are performed to investigate the effect of wing sweep on the characteristics of the leading-edge slat noise of the 30P30N high-lift research model. These measurements are conducted in the anechoic wind tunnel facility at

Based on Amiet's theory formalism, we propose a numerical framework to compute the aeroacoustic transfer function of realistic airfoil geometries. The aeroacoustic transfer function relates the amplitude and phase of an incoming periodic gust to the

To obtain far field (aero)acoustic radiation characteristics a model is placed in an open test section wind tunnel with microphones positioned outside the flow. However for aerodynamic measurements a closed test section performs better. In stead of f
