Modeling vibrating panels excited by a non-homogeneous turbulent boundary layer

Predicting the vibration response of an elastic structure excited by a turbulent flow is interest for civil and military transportation sector. The models proposed in literature are generally based on assumption that boundary layer (noted TBL following) exciting spatially homogeneous. However, this not always fulfilled practice, particular when area close to starting point or with curved structures. To overcome issue, work proposes extend two approaches used dealing homogeneous TBL, namely spatial wavenumber approaches. extension approach non-homogeneous excitation relatively straightforward gives us reference, however costly computation. On contrary, extending requires more developments assumptions have led authors develop sub-area decomposition technique (SDT). It consists partitioning several sub-areas, assuming pressure field each neglecting certain interactions between sub-areas. A criterion size as function minimum wavelength wall basis numerical calculations. test case plate varying thickness growing allows highlight: (1) SDT compared classical calculation considering TBL; (2) efficiency terms computing time approach.
