Abstract

Wind tunnel measurements of wall pressure fluctuation were conducted at high subsonic Mach number. The data was analyzed in order to calculate the spatial decay of coherence of turbulent structures in the turbulent boundary layer as a function of the Strouhal number. The decay parameter determined from the measurements was compared with the predictions from the coherence length model of Efimtsov. The Mach number was varied in order to investigate the influence of a change in flow speed on the decay parameter for various Strouhal numbers.
