The SEMS computational aeroacoustics team presented their work at the 30th AIAA/CEAS Aeroacoustics Conference (Aeroacoustics 2024), which is the premier international forum for the field of aeroacoustics.

Well done to Dr Hussain Abid, Dr Vasily Gryazev, and Amal Murali, whose work on high-resolution unsteady aerodynamics and aeroacoustics modelling and data-driven analyses in the area of propulsive jet and open rotor noise was well received by top international experts from industry, government, and academia.

Of particular interest have been presentations of the group on new ways of extracting important insights about the dynamics of high-speed turbulent flows using dynamical system and machine learning techniques. Such techniques can be used to develop new noise reduction technologies to make jet noise aircraft quieter.

The presentation on the new efficient computational approach for predicting noise from an open rotor immersed in a thick wall boundary layer also attracted considerable attention. This type of installation is typical of new generation of aircraft, using boundary layer ingestion propulsion systems. The latter propulsion systems are very fuel efficient and well aligned with the current drive towards the decarbonization of aviation. However, their community noise produced by turbulence interactions remains the major unsolved problem for public acceptance. Hence, new efficient computational techniques such as developed by Queen Mary researchers will enable the acoustic optimisation of the existing designs, thereby reducing the time it takes for the new propulsion technologies to be delivered to the market.
