A Theoretical Study of Leading Edge Noise
2008
Glegg, Stewart
The report describes a theoretical procedure for calculating leading edge noise which addresses the differences found between current theoretical calculations and wind tunnel measurements of unsteady lift on airfoils in turbulent flow. The results have been compared with experiments carried at in a companion study at Virginia Tech by Dr. William Devenport. It was concluded that the effect of angle of attack on the radiated noise is relatively weak but the effect of thickness is to reduce the radiated sound levels at high frequencies.
