Abstract

In this study, the propergation of a weak periodic disturbance to pressure fluctuations on a flat rectangular cylinder was investigated to understand the mechanism of the expansion of the spatial correlation of the fluctuating lift. By the ensemble averaging of the fluctuating pressures, it was clarified that the strength of the disturbance given to the stagnation point didn't affect to the region of the propergation of a periodic disturbance to pressure fluctuations.
