Industrially Oriented Jet Noise Reduction TechnologiesDate: Dec. 1, 2021 - Dec. 3, 2021
With the aim of reducing the environmental impact of noise caused by aircraft during take-off, the prediction and mitigation of jet-airframe interaction noise sources remains a significant challenge for integrated propulsion-airframe architectures. The ambition of the DJINN (Decrease Jet Installation Noise) project is therefore to develop a new generation of reliable computational fluid dynamics (CFD) methods, most of them belonging to the field of hybrid methods, for assessing promising noise-reduction technologies, with support and validation from reduced-scale experiments.
This key ambition of the DJINN CONFERENCE is tied to the provision of advanced tools for coupled aerodynamics-aeroacoustics to enable design optimisation in future industrial environments and to reach a new level of noise reduction through a highly collaborative effort – with the main innovative objectives targeting at industrial needs:
The DJINN (Decrease Jet Installation Noise) initiative is an EU H2020 project coordinated by CFD-Berlin.
Contributions by participants are expected according to the listed topics:
H. Xia (Loughborough University):
“Developing modelling and simulation techniques for high St jet noise.”
M. Azarpeyvand (University of Bristol):
‘An overview of jet noise research at the University of Bristol’
It is of importance for the DJINN project to interact with colleagues from outside the DJINN consortium. Therefore, at the DJINN CONFERENCE two test cases (both isolated and installed nozzle geometries) will be made available including comprehensive data sets for computation.
All obtained results will be gathered well before the second DJINN CONFERENCE - close to the end of the DJINN project, i.e. about 1.5 to 2 years after this first conference.
Please note that running a test case is NOT mandatory for registration.
To be noted that there is no early bird registration.
