Understanding the physics of the pressure fluctuations induced by turbulent boundary layers is of major theoretical and practical importance. From a practical point of view, an in-depth knowledge of the nature of boundary-layer-induced pressure fluctuations is essential to the structural design of launch vehicles and to the generation of background noise in wind-tunnel facilities. From a theoretical point of view, pressure fluctuations are an important ingredient in turbulence as they appear in statistical correlations such as the pressure-strain correlation terms that redistribute turbulence among different components of fluctuating velocity.
