Effect of Inflow Conditions on the Noise Reduction Through Leading Edge Serrations

What is it about?

Leading edge serrations, inspired by Humpback whales and owls, are a promising passive application for the noise reduction of airfoils and turbomachines. Applying an array-beamforming technique enables us for the first time to experimentally localise the regions of noise reduction and to define the isolated reduction capability by reducing the influence of noise sources that are non-related to the serrations.
