Experimental data to accompany the paper ‘Wall Pressure Fluctuations In An Axisymmetric Boundary Layer Under Strong Adverse Pressure Gradient’ Journal of Fluid Mechanics

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.

本数据集配套发表于《流体力学杂志》（Journal of Fluid Mechanics）2023年已接收待刊论文《强逆压力梯度下轴对称湍流边界层的壁面压力脉动》（Wall pressure Fluctuations in an axisymmetric turbulent boundary layer under Strong Adverse Pressure Gradient），作者为Balantrapu N. A.、Alexander W. N.与Devenport W. J.。本数据集针对与车辆构型（vehicular configurations）相关的轴对称物体表面湍流边界层（turbulent boundary layer）下的壁面压力脉动开展了记录与研究，旨在揭示其内在物理机制，同时为湍流建模（turbulence modelling）与气动声学预测（aeroacoustics predictions）的改进提供支撑数据。上述论文中讨论了壁面压力的频谱（Spectra）及时空特性（space-time characteristics），及其与主导湍流流动（overriding turbulent flow）的关联。本文将呈现该数据集的相关实验数据。
