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
