Flow Noise

This book highlights the importance of sound produced by fluid flow or flow-induced noise. Noise created by unsteady flow creates high levels of environmental noise pollution, a known public health problem, and can compromise the acoustic qualities of marine vessels. There is a seemingly ever-growing list of modern technology that created flow-induced noise which includes aircraft, wind turbines, submarines, drones, high-speed rail, and cooling fans. More scientists and engineers are required to incorporate the effects of flow-induced noise in their work. This book also provides a comprehensive introduction to the theory underpinning the understanding of flow-induced noise.

Con Doolan obtained an honors degree in Mechanical Engineering and a Ph.D. in Aerospace Engineering from the University of Queensland. After working at the University of Glasgow, Department of Defence (Australia), and University of Adelaide, he is now Professor at the University of New South Wales, Sydney, and leads the Flow Noise Group. His research is focused on aeroacoustics or the production of sound from unsteady fluid flow. Current projects include the control of airfoil noise using novel perforated and poroelastic materials, hydroacoustic noise, wind turbine noise, and understanding the acoustics of supersonic, reacting flows. Danielle Moreau obtained her Bachelor of Engineering (hons) and Ph.D. from the School of Mechanical Engineering at the University of Adelaide in 2005 and 2010, respectively. Following Ph.D. completion, she was employed as Postdoctoral Research Associate at the University of Adelaide for five years. She is now Senior Lecturer in the School of Mechanical and Manufacturing Engineering at the University of New South Wales, Sydney. Her current research focuses on the understanding and control of flow-induced airfoil noise to aid the design of quiet modern technologies such as aircraft, marine vessels, wind turbines, and drones.
