Aeroacoustics of wall-bounded turbulent flows
Aeroacoustics of wall-bounded turbulent flows
Direct numerical simulations of turbulent plane Poiseuille and Couette flow are used to study fluctuating wall pressure and shear stress. For both flows the wave-number–frequency spectra are found to be nonzero in the limit of zero wave number, which has significant implications for theoretical work. Peaks in the spectra are consistent with convective phenomena, and typical convection speeds are derived for both cases. The sensitivity of the results to Reynolds number and numerical parameters is discussed.

Abstract
Direct numerical simulations of turbulent plane Poiseuille and Couette flow are used to study fluctuating wall pressure and shear stress. For both flows the wave-number–frequency spectra are found to be nonzero in the limit of zero wave number, which has significant implications for theoretical work. Peaks in the spectra are consistent with convective phenomena, and typical convection speeds are derived for both cases. The sensitivity of the results to Reynolds number and numerical parameters is discussed.
