Characterization of acoustic sources in a corrugated pipe flow with linear stochastic estimation

The intense whistling of corrugated pipe under flow is related to a coherence between the dynamics of structures developing in the shear layer over cavities and acoustic eigenmodes of the pipe. In order to highlight the coupling between aerodynamics and acoustics, three measurement systems with comp...
