(From CHANG Daoqing of Key Laboratory of Noise and Vibration Research) On September 2, 2011, Prof Jeremy Astley visited Institute of Acoustics, Chinese Academy of Sciences (IACAS) and made a report entitled "Computational Aero-Acoustics, CAA( for Aircraft Noise Prediction )". The report was chaired by Prof. Yang Jun, and many researchers and students participated in it.
His report includes two parts. The first part is "Introduction to Institute of Sound and Vibration Research,University of Southampton." The history and main research area of ISVR were introduced. The second part is "Rolls-Royce UTC in Gas Turbine Noise". Three topics in this part were presented. Topic A was 'Duct acoustics, nacelles, liners' .Topic B was 'Fan and turbo-machinery noise'. And topic C was 'Jet and exhaust noise'. This report describes both the numerical results in-depth and experimental results of turbine noise that arouses heated discussions around the participants, enhances the mutual understanding and communication in the CAA for aircraft noise prediction.
Dr Jeremy Astley joined the Institute of Sound and Vibration, Southampton University in March 2001 as Professor of Computational Acoustics, and is attached to the Rolls-Royce University Technology Centre in Gas Turbine Noise. He graduated in Mathematics from the University of Canterbury in Christchurch New Zealand and completed a PhD in mathematics at Bristol University in 1973. Since then he has held academic positions at the University of Nottingham, the University of Missouri-Rolla, and the University of Canterbury. He has also held visiting fellowships at the Universities of Hull and Durham. He is a fellow the Royal Society of New Zealand and of the Institution of Professional Engineers of New Zealand and the recipient of a Doctorate of Engineering in 2000 for contributions to Finite Elements in Acoustics. He is currently the Director of the Rolls-Royce Technology Centre for Gas Turbine Noise at the ISVR. He has played a leading role in applying finite and boundary element methods to a broad range of problems in acoustics and is the author of more than 50 articles on this topic published in refereed international journals. He serves on the editorial board of the 'International Journal for Numerical Methods in Engineering' and 'Communications in Numerical Methods in Engineering'. And is an associate editor of the Journal of Sound and Vibration and for the AIAA Journal.
