Abstract Direct numerical simulations (DNS) of turbulent channel flows up to ${Re}_{\tau} \approx 1000$ are conducted to investigate the three-dimensional (consisting of streamwise wavenumber, spanwise wavenumber and frequency) spectrum of wall pressure fluctuations. To develop a predictive model of the wavenumber–frequency spectrum from the wavenumber spectrum, the time decorrelation mechanisms of wall pressure fluctuations are investigated. It is discovered that the energy-containing part of… 
Resolvent analysis of pressure fluctuations in turbulent channel flows
We study pressure fluctuations in direct numerical simulations (DNS) of turbulent channel flows at friction Reynolds numbers of approximately 180 and 550, by a comparison between analysis of DNS data


Measurements of the wavenumber-frequency spectrum of wall pressure fluctuations under turbulent flows
The prediction of the vibratory response of structures excited by turbulent flows implies a good knowledge of both aerodynamic and acoustic components of the wall pressure fluctuations. In the

Pressure fluctuations in a turbulent channel flow are investigated by analysing a database obtained from a direct numerical simulation. Detailed statistics associated with the pressure fluctuations
Wall pressure spectra calculations for equilibrium boundary layers
Assuming information about the mean velocity and vertical turbulent velocity, it is possible to calculate the flow direction wavenumber spectrum of pressure fluctuations ϕ(k1 δ)/τ02δ. The law of the
Spectral features of wall pressure fluctuations beneath turbulent boundary layers
Experimental measurements of the frequency spectra and frequency cross‐spectra of the wall pressure fluctuations beneath a turbulent boundary layer were made in a low‐noise flow facility. The data,

The paper is discussion of measurements of the statistical properties of the pressure field at the wall of turbulent attached shear flows. These measurements have been made only in part by the
A new model for the cross spectrum and wavenumber-frequency spectrum of turbulent pressure fluctuations in a boundary layer
A model is developed for the statistical characteristics of the turbulent pressure field in a boundary layer. It is shown that the coherence scales are limited at low frequencies by the finiteness of
Modeling the wall pressure spectrum in turbulent pipe flows
An important source of vibration and noise in piping systems is the fluctuating wall pressure produced by the turbulent boundary layer. One approach to calculating the wall pressure fluctuations is
Analytical models of the wall-pressure spectrum under a turbulent boundary layer with adverse pressure gradient
This paper presents a comprehensive analytical approach to the modelling of wall-pressure fluctuations under a turbulent boundary layer, unifying and expanding the analytical models that have been
