@article{Maxit2019DiscussionAD, title={Discussion About Different Methods for Introducing the Turbulent Boundary Layer Excitation in Vibroacoustic Models}, author={Laurent Maxit and Marie Noel Berton and Christian Audoly and Daniel Juv'e}, journal={arXiv: Applied Physics}, year={2019}, pages={249-278} }

For controlling the noise radiated from vibrating structures excited by turbulent boundary layer (TBL) it is relevant to develop numerical tools for understanding how the structure reacts to TBL excitation. Usually, the wall pressure fluctuations of the TBL are described through statistical quantities (i.e. space-frequency or wavenumber-frequency spectra) which depend on the TBL parameters. On the other hand, the vibro-acoustic models (i.e. Finite Elements, Boundary Elements, Transfer Matrix…
