Context: The H2020 Center of Excellence in Combustion project (CoEC), which gathers combustion research laboratories across Europe, is aligned with the goals of decarbonization of the European power and transportation sectors and Europe ́s vision to achieve net-zero greenhouse gas (GHG) emissions by 2050. The project is a contribution of the European High-Performance Computing combustion community to a long-term EU greenhouse gas emissions reduction in accordance with the Paris Agreement by supporting the EU leadership with the development of advanced power and propulsion technologies by the use of Exascale computing. This Center of Excellence proposes a coordinated research and innovation effort to make low and zero-carbon solutions economically viable and further develops new solutions not yet mature to higher Technology Readiness Level (TRL). The CoEC is conceived to handle massive use of big data and extreme-scale computing to harness the outstanding capabilities of the upcoming Exascale systems.
The objectives of the contract in the CoEC project are centered around the simulation of spray combustion at the exascale. The first objective is to add mass and heat transfers to the existing interface-capturing atomization models in the YALES2 platform. This model will be based on a two-fluid formalism in order to guarantee control of the fluxes at the interface. After extensive validation of the model, it will be coupled with the dynamic adaptation of unstructured meshes (AMR). These algorithms will have to be optimized to exploit the current pre-exascale machines. The final model will be used to carry out Direct Numerical Simulations (DNS) of spray combustion with very high fidelity.
The candidate must have a PhD in Mechanical Engineering or Applied Mathematics
- Computational Fluid Dynamics, Numerical analysis, Object-Oriented Programming
- Language skills
- Writing skills in English, ability to formulate/work on a scientific project
- Ability to work in a team
Applications must include a detailed CV and a one-page résumé of the PhD dissertation.; at least two references (people who may be contacted); a cover letter of one page.
CORIA is a CNRS joint laboratory with INSA and University of Rouen. CORIA is a Mechanical Engineering Lab (200 people) fully devoted to reacting flows. This includes main interests in different fields as combustion, plasmas, spray studies, energetic processes. Approaches are experimental, with a great emphasis on optical methods as well as theoretical, through modeling of reacting flows. The laboratory is thus developing experimental diagnostic as well as new theoretical tools. Its mission is to provide excellence in scientific research and development, and it maintains strong links with industry.
