SoTiC 2023

Symposium on Thermoacoustics in Combustion:
Industry meets Academia​

11-14 September 2023 ● ETH Zurich ● Zurich, Switzerland

Although understanding and avoiding of thermoacoustic instabilities is of equally outstanding relevance in the design of gas turbine combustors as well as rocket engines, two almost separate research networks have evolved around these two industries. Both have developed their respective research strategies and methodologies. The two research branches successfully met in 2016 and 2021 at the first two Symposia on Thermoacoustics in Combustion (SoTiC) organized at TUM. In order to continue stimulating the exploitation of potential synergies, the third SoTiC was organized in 2023 at ETH Zürich, with the aim of again providing a forum for specialists from all related industries and their academic counterparts.
Anticipated benefits were discussions on and exchanges of practical experiences, experimental and analytical methods, physical interpretations, and future visions in the field of combustion dynamics. Invited speakers from both industry and research groups presented their specific views on key topics of current thermoacoustic research. Covered topics:

  • Annular, Can-Annular and Transverse Modes
  • Dynamics of Spray and Autoignition Flames
  • Generation, Propagation and Damping of Perturbations
  • Machine Learning, Artificial Intelligence and Data-Driven Methods
  • Nonlinear and Stochastic Phenomena
  • Passive and Active Control of Instabilities
  • Physical Mechanisms, Flame Response
  • Pressure and Fuel Effects
  • Stability Analysis and Uncertainty Quantification
  • Tools and Methods Development
The proceedings of the symposium are available to all registrants in electronic form.
All SoTiC 2023 registrants had the opportunity of recommending two best papers on the basis of outstanding writing quality, a high degree of originality, and an unusual contribution to science and engineering. Both awards are endowed with 500€ each. The Best Fundamental Paper Award recognizes the publication with the greatest contribution to fundamental understanding in the field of thermoacoustics, and the Best Technical Paper Award recognizes the publication with the greatest technical relevance of all papers submitted to SoTiC 2023.
Selected papers presented at the symposium will be published in a special issue of the International Journal of Spray and Combustion Dynamics after peer review.
