About HyNOISE
HyNOISE is a Doctoral Network aimed to train doctoral candidates able to face current and future challenges in the prediction and control of direct and indirect noise generated by hydrogen flames. Four specific research objectives will be pursued:
- Unveil the dynamics and sound pressure level generated during unsteady ignition and flashback process
- Investigate the direct broadband sound generated due to the coupling between unsteady flame dynamics and flame-flame interactions, hydrodynamic and thermo
- diffusive instabilities, and turbulence.
- Understand physical mechanisms leading to the onset of thermoacoustic instabilities coupled with different modes at either with a specific focus on high frequencies
- Study the contribution of convective waves to combustion noise and thermoacoustic instabilities. Multiple hydrogen-air archetypes typical of air-breathing hydrogen combustion systems in both single and annular multi-injector configurations will be investigated. In a collaborative partnership between academic and industry partners who are major European gas turbine manufacturers,
HyNOISE bring relevant expertise together and to pursue solutions for hydrogen through integration and combination of unique and advanced theoretical, high-fidelity modelling and experimental expertise. This will lead to the development of new models and tools able to correctly predict hydrogen flame dynamics and its resulting pressure field, and, on this basis, developing control and mitigation methods to overcome current limitations in hydrogen combustion systems and design innovative, quiet, and stable combustion devices. The technologies developed will stimulate the green transition in the power generation and transport sectors, thus contributing to the achievement of the EU's challenging decarbonization goals.
About the host organization
POLIBAis a public research university located in Bari, Italy. It is one of the largest in the south of Italy and currently has more than 11,000 students enrolled. Among others, POLIBA houses the Department of Mechanics, Mathematics and Management (DMMM). DMMM carries out higher education, research and technology transfer activities at its Bari and Taranto sites. The DMMM stands out for excellence in industrial research in the areas of mechatronics, energy, aerospace, industry 4.0, enabling technologies and sustainable development.
DMMM received the prestigious "Department of Excellence" award from the Italian Ministry of University and Research (MUR) for the five-year periods 2018-2022 and 2023-2027.
Individual Research Project (IRP)
The main objective of this research is to investigate, through high-fidelity simulations (DNS and LES), the noise generated by abrupt flame dynamics in hydrogen flames, with particular focus on flame quenching driven by flame–wall interactions (FWI) and boundary-layer flashback (BLF). Several flame types will be explored to identify and characterise the underlying mechanisms responsible for acoustic emissions. Task:
- As a first step, and as a continuation of the DC7 study, FWI and BLF dynamics will be examined using high-fidelity DNS to gain a fundamental insight into noise-generation mechanisms. Three-dimensional canonical lean hydrogen–air premixed flames will be considered to assess how thermodiffusive instabilities interact with flame–wall processes and influence the resulting acoustic field.
- Subsequently, the AVBP modelling developments from WP3 will be employed to evaluate the capability of the new H2-TFLES framework to accurately capture flame–acoustic coupling. This framework will be applied to LES of the NTNU and UC3M experimental configurations. The simulations will complement experiments, demonstrating the ability of the modelling approach to reproduce measured sound-pressure levels and improve understanding of the coupling between flame–wall interactions, flame quenching, and acoustic emissions.
- Finally, a low-order model (LOM) capable of predicting sound-pressure levels will be proposed as an extension of existing m
