Abstract

Near-field aeroacoustic sound and the wall surface static pressure fluctuations of the suction side of a fan blade were measured simultaneously. Proper orthogonal decomposition (POD) analysis and correlation analysis were applied to the measurement results. It became clear that the near-field aeroacoustic sound shows the highest values near the reattaching point and has a high correlation with the first mode of the wall surface static pressure fluctuations.
