Popis:	Statistical turbulence properties of turbulent flow over a two-dimensional rib which was flush mounted on a wind tunnel wall was extensively surveyed. Velocity fluc- tuations in the turbulent separated and reattaching flow and wall-pressure fluctuations on the rib and its downstream surface were obtained by using a split-fiber hotwire anemometry and a 32-channel microphone array, respectively. Distribution of the wall static pressure was acquired by using a Scanivalve system. Statistical quantities of the turbulent separated and reattaching flow were determined in terms of wall static pressure distri- bution, profiles of the streamwise velocity and its fluctuations, wall pressure fluctuation coefficient, and wall-pressure spectra. Characteristics of the shedding large-scale vortical structures buried in the turbulent flow were disclosed.
