Reference: CFD-2022-DOM-02 Location: 42 avenue Gaspard Coriolis – 31057 Toulouse Team: CFD Contact person: Jérôme Dombard Research unit: Advanced Aerodynamics and Multi-Physics E-mail: dombard@cerfacs.fr Salary: 40 K€/year (gross) Duration: 1 year Starting date: june 2022 Level of education required: PhD HOST LABORATORY The Cerfacs is a fundamental and applied research center specializing in modelling and digital simulation. Through its resources and expertise in high- performance computing, it addresses major scientific and technical problems in public and industrial research. The Cerfacs teams develop innovative methods and software solutions to meet the needs of the aeronautics, space, climate, energy and environment sectors. Cerfacs works in close interaction with its seven associates: Airbus, Cnes, EDF, Météo France, Onera, Safran and TotalEnergies. HOSTING TEAM The CFD (Computational Fluid Dynamics) team is the largest team at CERFACS. It focuses on the simulation of flows by developing advanced numerical methods and applying them to aircraft, rockets, helicopters, car engines, turbines, etc. This team develops essential tools in many application fields with a well-known leitmotiv in industry today: let's calculate systems (aircraft, engines, etc.) before building them. JOB DESCRIPTION Topic(s): Turbomachines Aerodynamics Numerical Methods Context: The need for representativeness of LES calculations of industrial type isolated turbine is based today on two decisive elements: 1) the ability to specify a flow in turbine inlet in agreement with the evolution in space and in time leaving the combustion chamber and 2) to be able to guarantee the good turbulent activity and the associated mixing at the level of the vein and around the blades. Mission: The first objective of this postdoctoral offer is to work on more realistic boundary conditions at the inlet. For example, recently, the so-called SPOD analysis method by Benjamin Martin [1] has demonstrated its ability to correctly extract the unsteady flow and temperature fields. Once used and exploited, this decomposition can therefore be used to specify an isolated turbine calculation with the ability to reproduce very accurately the reference case, unlike a modeling approach based on assumed spectra and the generation of a so-called synthetic turbulent field. The second part of the postdoc will be devoted to the application of static mesh adaptation libraries (MMG3D - CERFACS/INRIA collaboration) and on turbomachine type configurations [1] Generation of Realistic Boundary Conditions at the Combustion Chamber/Turbine Interface Using Large-Eddy Simulation.
