S02 Combustion Noise and Thermo-acoustics
Maria Heckl

Unsteady combustion generates sound. A particularly violent form of combustion noise tends to arise if the combustion takes place in an acoustic resonator, because then the heat release rate and the sound field can interact in such a way that they amplify one another, generating a “thermo-acoustic instability”. This can lead to structural damage in gas turbine combustors and some types of aircraft, so avoiding thermo-acoustic instabilities is paramount. They are a complicated phenomenon, involving sound waves, combustion, aerodynamic effects and structural waves, as well as the interaction between all these. The aim of this session is to bring together scientists with an academic and/or industrial background in this area. It complements the session on “Combustion dynamics: acoustics, vibration and fatigue”, which focuses on computational fluid dynamics and experimental aspects of combustion-induced acoustics, and which is organised by Dr Jim Kok, University of Twente, NL. Suggested topics of the current session include, but are not limited to the following: Modelling of the thermo-acoustic feedback with analytical and numerical methods; Nonlinear effects; Active control of combustion noise and thermo-acoustics; Modelling of the acoustic source processes with a view to application in analytical and numerical methods; Sound propagation in combustors with non-uniform properties; Boundary condition modelling and measurements; Physical processes involved in the generation of combustion noise.

S11 Nonlinear Acoustics and Vibration
Woon Siong Gan

Nonlinear acoustics and vibration has become increasingly important during the last thirty years due to the exponential increase of computation power and increasingly higher sensitivity of electronic instrumentation.  It is a broad field which encompasses large amplitude sound waves and vibration. The nonlinearity of materials results in nonlinear effects which arise from defects in the materials.  Applications include nonlinear nondestructive evaluation, harmonic medical ultrasound imaging, high intensity focused ultrasound for noninvasive surgery, cavitation, and control of high intensity jet noise and development of new materials such as nanocomposite materials.  Also included are the phenomenon of chaos which has become popular during the last twenty years with the establishment of institutes of nonlinear science and complex systems in universities and research centres. In addition journals are now dedicated to this subject.  Chaos theory is used today even in the prediction of price movement on stock markets.  I have been organizing structured sessions on nonlinear acoustics and vibration since ICSV5 in Adelaide, Australia in 1997.  I have also witnessed the growth in this field demonstrated by the increasing number of papers to the current number of twenty to thirty papers presented at each ICSV congress.

S13 Structure-Borne Sound in Buildings
Barry Gibbs

This session will consider methods of measuring and predicting structure-borne sound in buildings due to mechanical services systems and domestic appliances. The mechanical services include: heating and ventilation systems, piped water systems, internal transportation systems and stair systems. Domestic appliances include: central heating units, washing machines and cleaning and food processing appliances. Until recently, the complexity of the structure-borne sound transmission and propagation process has prevented the development of measurement and prediction methodologies of use to manufacturers, building engineers and legislators concerned with noise control. However, there has been progress in the prediction of noise resulting from impact and vibration sources in heavyweight homogeneous building structures. There also has been some progress for the case of lightweight non-homogeneous constructions. This session welcomes papers on vibro-acoustic source characterisation and on methods of predicting the resultant sound pressure levels in buildings. The session will be of interest to researchers who are developing laboratory test procedures for characterising sound sources and also the transmission characteristics of walls and floors, including impact sound; also, for those implementing recently introduced standard prediction methods for airborne and impact sound transmission between rooms. Papers on the performance of lightweight constructions are particularly welcome.

S14 Active Noise and Vibration Control in Practical System Implementations
Sven Johansson
sven.johansson@bth.seLars Hakansson

The purpose of this structured session is to report on the latest research and development works carried out in different areas of practical applications and installations of active noise and vibration control systems. Computer experiments and simulations are important in the development of control systems, but these kinds of performance evaluations cannot fully take the place of practical experiments. Practical experiments are very important in the evaluation of a control system. Practical experiments are also of high importance in order to receive a deep understanding of the performance of active control applied to a physical system and design of such systems. Papers presented in this session will focus on experiments carried out in research laboratories or in practical installations in vehicles or in industrial applications. The papers can, for example, treat algorithm design, system design and configurations, implementation aspects, actuator design, installations and arrangements of control sources and error sensors.

S18 Combustion Dynamics, Acoustics, Vibration and Fatigue
Jim Kok

A combustion process fluctuating with time will act like an acoustic source. Particularly in gas turbine combustors with their high power density and highly turbulent flow the dynamic combustion process may induce high amplitudes in pressure fluctuations and generate vibration of structural components. The vibrations will also have an effect on the heat transfer. Ultimately fatigue and creep will lead to failure of the structure. The aim of the session is to present and discuss the most recent work on numerical modeling and experimental research in this area, with a target to limit cycle oscillations. There is also a session on “Combustion noise and thermo-acoustics”, which focuses on analytical aspects of combustion-induced acoustics, and which is organized by Dr. Maria Heckl of Keele University. Typical topics in this session will be on numerical modeling or experimental research on: Characteristics of interaction between transient combustion and acoustics; Effects of elevated mean gas pressure and temperature; Thermo acoustic stability and limit cycle behavior, nonlinear processes; Fluid-structure-interaction by means of acoustic oscillations in combustion flows; Interaction of heat transfer and acoustic oscillations. Fatigue and vibration of gas turbine combustors.

S19 Underwater and Ship Acoustics
Nicole Kessissoglou

In underwater acoustics, passive and active sonar systems are used for undersea detection purposes as well as for various forms of sensing. Underwater acoustics is also used for communications by whales and other marine mammals. Underwater noise is generated by natural sources such as wind and waves, as well as by ships, submarines and marine platforms. Reduction of underwater noise from maritime vessels is of importance for the reliable operation of onboard sensitive instruments (in the case of research vessels), to minimise detection by hostile sensors (in the case of defence vessels), and to reduce the environmental impact of underwater noise on marine life.

Acoustic signature is used to describe the combination of acoustic emissions of ships and submarines. It is combined of individual noise sources which include machinery noise, cavitation noise and hydrodynamic noise. The major sources from maritime vessels contributing to underwater noise are due to the onboard machinery, propeller and background hull flow noise.

Papers in the field of underwater and ship acoustics cover a wide range of topics, including but not limited to, noise generation by ships including hydrodynamic noise, machinery noise and noise reduction; underwater noise propagation; underwater communications; target strength, scattering and reverberation; shallow water effects including seafloor and sediment acoustics; ocean variability; bioacoustics including noises made by fauna and the impact on marine fauna from anthropogenic noise sources; signal processing techniques.

Thermoacoustic Technologies: from Fundamentals to Applications
Artur J. Jaworski
Thermoacoustic Technologies are a relatively new interdisciplinary topic in science and engineering combining the fundamental areas of acoustics with fluid mechanics, heat transfer and acoustic/electrical transduction. It is broadly concerned with a direct conversion of heat into sound, or using intense sound to transport heat. When a porous solid body (stack/regenerator) is immersed in an intense acoustic wave, the cyclic expansion and compression of the gas, coupled with its movement, leads to a thermodynamic process similar to a Stirling cycle, which in turn can cause localised cooling and heating of the solid body, producing large temperature differentials. In a reverse effect, a high temperature differential imposed along the solid leads to a spontaneous generation of an acoustic wave, a form of useful work that can be converted to electricity. These effects are utilised in thermoacoustic coolers, heat pumps and engines.
There are clear technological and environmental benefits of thermoacoustic systems. Firstly, their engineering complexity is significantly reduced: a thermoacoustic engine is essentially a pressurised network of acoustic ducts with heat exchangers and stacks/regenerators – having no moving parts – which generates useful work. This is a major advantage in applications where frequent maintenance is not possible. Secondly, they are environmentally friendly: the working medium is usually an inert gas such as helium, neon, argon or xenon, or their mixtures; cheaper systems can just use air. Finally, they are potentially low-cost due to their simplicity, low maintenance and use of inexpensive parts, materials and working media.
The session is designed to attract both practising engineers and academic researchers working in the area of Thermoacoustic Technologies. Papers related to theoretical modelling of thermoacoustic systems or their components, experimental methods dedicated to evaluating system or component performance as well as prototyping activities for thermoacoustic devices are equally welcomed in this session. (Please note that this session does not deal with thermoacoustic instabilities in combustion, which is a subject of a separate session at ICSV19)

Mark Asselineau
m.asselineau@peutz.frIn this session, we want to include papers on use of the absorptive treatment in spaces such as entrance halls, corridors, waiting rooms, and restaurants, and production facilities (offices and manufacturing halls). Typical questions to be discussed are: which acoustical parameter should be used (e.g. reverberation time, spatial sound level decay, background or ambient noise levels), which values should be set to those parameters, which regulations or standards should be used, what kind of acoustical treatment should be applied (e.g. Kinds of ceilings, noise barriers, noise generators, etc.).

S31 Noise and Vibration Diagnostics and Advanced Measurement Techniques
Naval Agarwal
naval.k.agarwal@boeing.comEffectively measuring and understanding sources of noise and vibration is critical to identifying effective solutions. During the testing phase or in-service noise and vibration concerns, noise and vibration engineers have the difficult task of identifying offending noise sources and/or their transmission paths. Once the source is identified, generally treating the source is more weight- and cost-effective. This session will cover the broad areas of advanced measurement and diagnostic techniques through to the resulting innovative and cost-effective engineering solutions that can be easily implemented.
