Trailing-Edge Noise Modeling and Validation for Separated Flow Conditions

Kurzfassung

The framework for a semi-empirical model for the prediction of aerodynamically generated trailing edge sound from subsonic low Mach number 2D airfoils with mildly separated turbulent boundary layers is presented. Aerodynamic and acoustic measurements were performed and results indicate that the separated trailing edge flow noise can be modeled in a similar fashion to trailing edge noise generated by attached turbulent boundary layers. Comparisons with aeroacoustic measurements show agreement between prediction and results.
