Abstract

In the present paper the causality correlation technique is applied for the experimental detection of noise sources at the leading edge slat in a high-lift device configuration. Velocity measurements in the vicinity of the slat using PIV as well as pressure measurements at the surface of the leading edge of the main-wing are conducted. Synchronously microphone measurements in the far-field of the wing's suction and pressure side are performed. By calculating the cross-correlation between the obtained near- and far-field quantities, regularities in the near-field related to the radiated sound-field are identified. Results for different angles of attack are compared and analyzed.
