Distorted Turbulent Flow in a Shear Layer

Abstract

This report describes the work carried out under grant number N00014-10-1-0910 Distorted Turbulent Flow in a Shear Layer at Florida Atlantic University. The project was in collaboration with Dr. William Devenport of Virginia Tech, who has carried out wind tunnel measurements on the rotor system described in this report as part of a companion project. The overall objective of this study is to measure and predict the sound radiation from a rotor operating near a wall in a wind tunnel. Results are given showing the methods used to calculate the far field noise levels and how this is related to the distortion of the inflow turbulence as it enters the rotor.
