Seminar by Prof Con Doolan and A/Prof Danielle Moreau from UNSW Sydney

Date:	Monday 1 June 2026 13:30 - 15:00
Location:	QMUL, Mile End, Engineering Building 2.16

On Monday 1 June, Prof Con Doolan and A/Prof Danielle Moreau from Flow Noise Group of the School of Mechanical and Manufacturing Engineering, UNSW Sydney, will visit SEMS and give Seminar talks. See the short abstracts of the talks below.

Talk 1
Title: Leading edge noise generation in fixed and rotating frames

Speaker: Prof Con Doolan, Flow Noise Group, School of Mechanical and Manufacturing Engineering, UNSW Sydney

Abstract: The interaction of fluid turbulence with an airfoil is a fundamental problem of aeroacoustics that is limiting the development of aero/hydro propulsion systems, such as drones, urban air mobility vehicles and underwater propulsors. This talk will provide an overview of the low-Mach number experimental aeroacoustic capabilities at UNSW's Flow Noise Group. It will then present the results of recent experiments regarding noise generation from turbulence interaction with fixed-wings and the noise from rotating drone propeller blades. The uniqueness of these results is that they are able to measure noise sources on the blades simultaneously with the radiated sound. The results are able to provide new detail of the turbulence interaction in difficult to measure situations and provide a new data for the validation of prediction tools.

Talk 2

Title: The Noise Sources in Complex Wall-Bounded and Tip-Clearance Flows

Speaker: A/Prof Danielle Moreau, Flow Noise Group, School of Mechanical and Manufacturing Engineering, UNSW Sydney

Abstract: Flow-induced noise originates from the unsteady surface pressure produced by the interaction of flow structures and solid boundaries. This talk presents recent advances in identifying these flow structures to better understand the noise generation mechanisms in complex, three-dimensional flows. It will showcase recent aeroacoustic experiments conducted at UNSW Sydney on a finite wall-mounted cylinder immersed in a pressure gradient wall boundary layer and a tip clearance flow relevant to low Mach number ducted propellers. Simultaneous measurements of the flow, far-field noise and unsteady wall pressure using techniques such as high-speed particle image velocimetry, acoustic beamforming and arrays of wall pressure taps with the remote microphone technique have been performed to determine the chain-of-causality, linking the flow dynamics to noise emission.
