This dataset accompanies the paper ‘Wall pressure Fluctuations in an axisymmetric turbulent boundary layer under Strong Adverse Pressure Gradient’, Balantrapu N. A., Alexander W. N., Devenport W. J., Journal of Fluid Mechanics, in press, 2023. The wall pressure fluctuations under turbulent boundary layer over an axisymmetric body, relevant to vehicular configurations, is documented and studies to discover the underlying physics in addition supplying information towards advancing turbulence modelling and aeroacoustics predictions. Spectra and space-time characteristics of the wall pressure and its relation to the overriding turbulent flow are discussed are discussed in the stated publication. Here, the relevant data are presented.
