Experimental and numerical characterization of aerodynamic noise applied to moderate Reynolds number airflow

Résumé

In the study of aerodynamic noise, a tackling challenge is to understand the underlying aeroacoustic mechanisms leading to its generation. The current paper aims at contributing to the noise characterization by focusing on a moderate Reynolds number airflow circulating through a rectangular channel containing a trapezoidal obstacle near the outlet. The outcome of Large Eddy Simulation and acoustic experiments are compared for different experimental boundary conditions at inlet and outlet, and for different apertures below the obstacle.
