Unsteady Flow Distortion Past Blades: Sources of Noise Generation in Rotating Flows

Abstract

Objectives: Determine flow structure at leading- and trailing-edges of blading in terms of velocity gradients representing pressure sources. Employ active and passive control techniques to manipulate crucial phase shifts of vorticity fields past blading.
