Introduction to Aeroacoustics and Self-Sustained Oscillations of Internal Flowso understand various aspects of self-sustained oscillation due to the coupling of vortex shedding with acoustic standing waves in a resonator. This approach is used to analyse the convective energy losses at an open pipe termination, human whistling, flow instabilities in diffusers, pulsations in pi

Broadband Noise from Lifting Surfaces Analytical Modeling and Experimental Validationstical declination of the formalism is introduced, relating the source statistics to the PSD of the acoustic pressure in the far field. Finally the statistical models are assessed against experimental data.

Boundary layer noise Part 1: generation mechanismsand a review of the most effective theoretical models predicting statistical quantities is given. The discussion is completed by a short review of the pressure behavior in realistic situations, including the separated boundary layers in incompressible and compressible conditions and the effect of sh

Boundary Layer Noise – Part 2: Interior Noise Radiation and Controll kinetic energy and cavity acoustic potential energy..A reduced model problem is then analysed in detail by examining a small section of the enclosure flexible wall and assuming a heavily damped interior. In this case a simplified model is used, which considers a rigidly baffled flat panel with unb
