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

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
