Abstract:In this study, the far-field acoustics and near-field flow characterizing vortex formation at a wing tip has been investigated experimentally. Measurements have been taken on a rectangular planform NACA 0012 wing with a flat tip and an aspect ratio (span-to-chord ratio) of π΄π = π /π = 2 at a Reynolds number of π π = 1.5 Γ 10 4 , and a geometric angle of attack of πΌ = 5 β’ in the UNSW anechoic wind tunnel. Acoustic beamforming results obtained with a planar 64-microphone array show that tip noise is a promi… Show more
