Job Description
Missions
Sustainable Aviation Fuels (SAF), encompassing fuels synthesized from biomass or zero carbon electrical sources, offer a short-term solution for decarbonizing the aeronautical sector. Exhibiting main properties like conventional jet fuel, using SAF does not require completely redesigning current combustion chambers. However, given the diverse feedstock required to meet energy demands, SAF compositions may vary considerably. Recent studies indicate that these variations affect combustion chamber performance, influencing operability and emissions. Research engineers working on the design of future aeronautical combustion chambers are faced with new scientific challenges.
This program is part of the SAFARI project, a research industrial chair funded by ANR, Safran Tech, Safran Aircraft Engines and Safran Helicopter Engines. SAFARI project aims to gain fundamental insights into SAF combustion's multi-physic phenomena and develop numerical tools for designing future combustion chambers. Scientific challenges are to understand and model the effects of pressure, heat transfer, and fuel composition variability on flame dynamics and pollutant emissions, such as NOx and soot particles.
Activity
The objectives of the post-doctoral fellow are to extend the virtual chemistry method to two phase flow combustion by accounting for preferential evaporation effects. A dedicated virtual mechanism will be optimized for blends representative of SAF. The main difficulty will be to account for preferential evaporation, as it generates fuel heterogeneities in the gaseous fuel compositions, which can affect the chemical structure of the flame. The virtual scheme architecture will be extended in this task to include multiple fuels in the reactant side. A learning database will be generated from an ensemble of combustion elements solutions which covers the possible reactant compositions. Validations will be carried out by calculating premixed and non-premixed two-phase flow flames, considering multi-evaporation. Then, the virtual scheme will be coupled with a turbulent combustion model to perform Large Eddy Simulations of e-fuel turbulent flames. The method will be validated by comparing virtual chemistry solutions against experimental data.
