Mitigating and harnessing sound for renewables and power generation

25 November 2021

1:00 pm - 2:00 pm

Zoom Webinar


We will look at several cases studies spanning from high to low intensity sound applications for energy engineering and sound-structure interaction. The first case is the high speed jet noise, where focus will be given to crackle noise which appears in supersonic jets but difficult to capture using power spectrum analysis. Modelling and experimental findings will be presented. The second study case will be harnessing high amplitude sound waves for compressing plasma in a hydrogen fusion reactor, where high performance computations of fluid-sound-structure interaction will be discussed. The third study case is of small kinetic turbine blades, showing how small geometry alternations can significantly reduce tonal noise while also improving aerodynamic performance, where computational and experimental analysis will be presented. Finally as time permits we will touch again at sound-structure interaction in the linear sense.


Dr Avital is a Reader in fluids and acoustics at Queen Mary University of London. His research group focuses on high performance computations coupled with experimental studies using an anechoic chamber and wind tunnel tests. He is a fellow of the Royal Aeronautical Society and his main research interests are in renewables fluid machinery of wind, water and hydrogen fusion, water engineering, bio-fluids and air-disinfection. The talk relies on analysis produced by several PhD graduates, research fellows and through collaboration with General Fusion, St Louis University, Federal University of Rio de Janeiro, Beihang University, University of Leicester, Tel Aviv University and others.
