Description:
The control and minimisation of sound generation and
propagation due to noise from jet engines, airframes,
helicopter rotors, fast trains through tunnel exits, wind noise
due to high rise buildings, duct and fan noise of air
conditioning systems, etc. are significant engineering design
issues in today's environmentally conscious society. A key goal of aeroacoustics
is the development of effective modelling techniques for the analysis and control of
the radiated noise.
The class of problems raised here is very challenging, and involves the representation and preservation of sound characteristics over a wide range of length scales. Currently, the generation of noise appears to be well represented by analytical techniques. Also, development of numerical algorithms for the near field aerodynamic flows has made good progress. The rapid development of high performance computing technologies have resulted in computational strategies where both near and far field flows can be represented. However, there are a number of key issues that need to be addressed, including:
Control of numerical noise which may dominate the physical noise Numerical schemes are still required to enable sound waves to propagate in a non-dispersive and a low-dissipative manner
An abiding issue is a strategy to enable the integration of models that address the various components of the problem - sound generation and its propagation, over the whole range of length scales.
This 3-day conference will bring together academics and aeroacoustics practitioners, including those from relevant industrial sectors and environmental agencies, in order to review state-of-the-art methodologies, applications and current capabilities in aeroacoustics. Papers covering new mathematical models and numerical methods and experience with established methodologies in various engineering applications are welcome. The Conference will consist of invited speakers and contributed papers to address current aeroacoustics methodology from analytical, computational and experimental perspectives. Selected papers are to be published in a special issue of the Journal of Sound and Vibrations. Further details for paper selection will appear in due course.
