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
CERFACS (Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique) is a private research organization developing advanced methods for the numerical simulation and the algorithmic solution of large scientific and technological problems of interest for research as well as industry.
That requires access to the most powerful computers presently available. CERFACS is supported by seven shareholders (AIRBUS, Météo-France, EDF, CNES, SAFRAN, ONERA and TOTAL). It hosts several scientific teams covering several topics (climatology, fluid mechanics, parallel algorithms...) among which the CFD (Computational Fluid Dynamics) team is the largest.
The main fields of application of the CFD team are turbulent, unsteady and reacting flows. It has an internationally recognized expertise in combustion and aerospace propulsion.
The team has developed software to compute turbulent flows for aerospace, safety, pollution problems and these codes are used today by numerous research groups in Europe and in industry. CERFACS is one of the first research institutes to have developed the capability to simulate complex turbomachinery stages with high-fidelity methods such as Large-Eddy Simulations. CERFACS has taken part in more than 30 French National projects and 15 European projects.
CERFACS possesses its own computational machines and is used to be selected to compute on Euro-HPC JU supercomputers ( ).
Individual Research Project (IRP)
LES of turbulent reacting flows is a reliable and relevant tool to predict thermoacoustic instabilities of combustors operated with conventional fuels. LES allows to account for the entire complexity of the problem including the geometry, the compressible nature of the fluid dynamics and the flame/turbulence interactions. While validated for conventional fuels, burning H2 induces complex and new physical interactions. These new features require fundamental improvement of existing modelling strategies routinely used for kerosene or carbonated fuels. These new models will be validated for burners where high frequency modes appear: azimuthal modes in the MICCA combustor and high-frequency screech modes in the HYLON chamber of IMFT. The PhD student will be supervised by Dr.-HdR Thierry Poinsot, Dr.-HdR Laurent Gicquel and Dr.-HdR Guillaume Daviller.
