报告人:Prof. Hans Bodén(瑞典皇家理工学院)
Biography
Hans Bodén is a Senior Professor in Technical Acoustics at KTH, specializing in Signal Analysis and Experimental Techniques. He earned his Dr. Tech. in Technical Acoustics from KTH in 1989 and has since supervised approximately 20 doctoral and licentiate theses. Prof. Bodén has held numerous leadership roles, including President of the International Institute of Acoustics and Vibration (IIAV), President of the Nordic Acoustic Association (NAA), and President of the Swedish Acoustical Society. He has also been a long-standing member of the Editorial Board of the Journal of Sound and Vibration. He has coordinated and contributed to multiple EU projects, including FP5, Tempus, Erasmus+, and Marie Curie initiatives. His extensive collaboration network spans both academia and industry, working with leading institutions and companies such as Airbus, Rolls-Royce, BMW, DLR, ONERA, Tsinghua University, and many others. Prof. Bodén’s work has led to the development of acoustic source characterization techniques that are now standard in 1-D CFD simulation software for internal combustion engines, including GT-Power and AVL BOOST.
Abstract
The talk will start with information about KTH – Royal Institute of Technology and the Marcus Wallenberg Laboratory for Sound and Vibration Research. Acoustic liners as used in aeroengine applications will be introduced and some basics information will be presented. Some results from an EU-China cooperation project (IMAGE 2016-2019) will be presented as examples of liner designs. Finally remaining challenges and research trends in liner design and characterization will be discussed.

报告人:Prof. Mats Åbom(瑞典皇家理工学院)
Biography
Mats Åbom holds an M.Sc. in Engineering Physics (1978) and a Ph.D. in Technical Acoustics (1989), both from the Royal Institute of Technology (KTH) in Stockholm, Sweden. He served as Senior Specialist at ABB Corporate Research from 1996 to 2000 before returning to KTH as Professor in Technical Acoustics (2001–2021), becoming the first person to be promoted to this position at KTH.
During his tenure, he supervised 27 doctoral and licentiate theses and five two-year postdoctoral researchers. He also held several key leadership roles, including Head of the Marcus Wallenberg Laboratory for Sound and Vibration (2003–2015), Vice-Director of the Competence Centre for Gas Exchange (CCGEx, 2011–2021), and Director of the Centre for Sustainable Aviation (CSA, 2015–2021). Prof. Åbom also contributed actively to the wider acoustics community, e.g., by serving as Vice-President of the European Acoustical Association from 2014 to 2016. He is currently Professor Emeritus at KTH.
His research focuses on experimental methods and modelling of sound propagation and source mechanisms, with particular expertise in duct acoustics and rotating machinery—fields in which he is internationally recognized. He has participated in numerous EU-funded projects and collaborative initiatives with Swedish and European industry. His research output includes over 6,000 citations (h-index 36, i10-index >100) and 11 patents.
Abstract
In this lecture, we begin with a summary of the classical theory of aeroacoustics as originally proposed by Lighthill in 1951. The different source terms are defined, and the corresponding scaling laws for aeroacoustic sources are discussed. The second part of the lecture focuses on fan noise, which is of major practical importance across a wide range of applications - including HVAC systems for buildings and vehicles, industrial processes for cooling, ventilation, and drying, as well as household appliances such as vacuum cleaners and the cooling of electric motors, batteries, and electronic devices.
