Abstract

Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.
 
Description We have developed a high-resolution jet-wing high-resolution (LES) model for the Rolls-Royce SYMPHONY experiment. The use of Graphics Processing Cards and the advanced numerical method allowed us to compute both the flow and noise with sufficient accuracy for industry to further apply our method for design optimisation studies.
Results were reported at the AIAA Aeroacoustic conference in June 2020, 2021, 2022 as well as in AIAA J in 2022 and 2023.
Exploitation Route We have already been invited by Rolls-Royce to test the method we developed in their new H2020 project "DJINN" devoted to jet installation noise reduction.
This are exploring opportunities towards a further exploitation of our method for high Technology-Readiness-Level industrial projects in the framework of Innovate UK.
Our method is currently tested by Rolls-Royce who are potentially interested to make it a new design tool.

Description We have developed a fast high-fidelity computational method to conduct virtual experiments to reduce jet noise including the effect of a complex airframe geometry. Such method can be incorporated in a design optimisation loop by industry to develop new aero engine exhausts in a cost efficient way. Using this method we have pioneered the use of Large Eddy Simulations for aero-acoustic design optimisation of a chevron nozzle, which was previously impossible due to prohibitively long run times.
