ABSTRAKT

Static pressure fluctuations are an important ingredient in turbulence, e.g. in the pressure strain terms which redistribute turbulence among the different fluctuating velocity components. In the present study, both mean and fluctuating static pressure and wall pressure have been measured simultaneously in turbulent boundary layers. The pressure inside the boundary layer is measured with a specially designed probe. Results on mean and fluctuation distributions, spectra, Reynolds number dependence, and correlation functions are reported.
