A Wavenumber Approach to Modelling the Response of a Randomly Excited Panel, Part I: General Theory

Predicted and measured plate velocities induced by turbulent boundary layers

“…The boundary layer induced vibration and noise in aircraft have received much attention as discussed in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Among these references Graham [7] proposed a model to predict TBL induced noise in an aircraft.…”

A model of wall pressure correlation for prediction of turbulence-induced vibration

“…The response to TBL excitation was calculated by a wavenumber frequency approach similar to that described in , Maury et al (2002), it is detailed by , , Birgersson and Finnveden (2005). The response is thus given by a single integral, over the wavenumber domain, of the wavenumber frequency spectrum multiplied by the sensitivity function of the structure.…”

Simulation of the pressure field beneath a turbulent boundary layer using realizations of uncorrelated wall plane waves

“…From a theoretical point of view, there is no obstacle for extending it to predict the pressure radiated by the panel excited by a TBL. Indeed, the formulation in the frequencywavenumber domain of the radiated pressure can be achieved similarly to the panel vibration [39]. It is then easily to show that the ASD function of the radiated pressure can be estimated 985 from the superposition of the uncorrelated wall pressure plane waves as for the panel vibration (see Sec.…”

“…One can emphasize that these developments can be easily adapted for evaluating the noise radiated by the panel (see the details of the formulation in [38][39][40]). It is however outside the scope of the present paper which focus on the synthetize of the WPF and the 250 prediction of the panel vibration.…”

“…For example, the Goody [6] or Rozenberg [7] models can be used for the ASD function whereas the Corcos [2] or Chase [3] be found in the literature [38][39][40].…”
