Abstract

Measurements of flow induced wall-mounted finite airfoil noise have been taken in an anechoic wind tunnel to examine the influence of camber on tonal noise production. The airfoils have an aspect ratio (ratio of airfoil span, L, to chord, C) of \(L/C = 2\) and measurements encompass variations in camber of 0–8%. The results include far-field acoustic spectra and sound maps taken with a microphone array that reveal geometry effects on noise production.
