Kurzfassung
The noise generation of turbulent flows near the edges of airplanes and automobiles is a general design problem and its importance increases in times of growing traffic. Turbulent boundary layers being convected past the trailing edge into the wake are known to generate an intense, broadband scattering noise. In this feasibility study the high-speed PIV technique was applied to a generic trailing edge noise experiment as performed on a flat plate model in the Aeroacoustic Wind Tunnel Braunschweig (AWB). Trailing edge noise sources have been measured simultaneously with instantaneous velocity vector fields to relate the generated sound to the ensuing aeroacoustic source quantities. The first step towards a new procedure for trailing edge noise prediction, combining numerical methods with the high-speed PIV measurement, is presented.
