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 proposed over many decades. The Poisson equation governing pressure fluctuations is Fourier transformed...
