Postdoctoral position in atmospheric pollutants dispersion at the local scale
ONERA is the French Lab for Aerospace research. Its main objectives are to:
- Develop and guide research activities in the aerospace field;
- Design, develop and deploy the resources required to conduct this research;
- Disseminate, in collaboration with the authorities or organisations responsible for scientific and technical research, the results of research at national and international levels.
Project objectives and partners
The PPM project (Ensemble Prediction of atmospheric Pollutant dispersion for Micro-meteorological applications) focuses on the formulation of velocity and turbulence boundary conditions for micro-meteorological models. The aim is to estimate the boundaries conditions influence on micro-scale LES (Large Eddy Simulations) modeling and to quantify the related uncertainties.
The project involves 4 main partners:
- The CERFACS (European Centre for Research on scientific calculus) will conduct the ensemble LES and LBM simulations and perform work on uncertainty quantification.
- The CNRM (National Centre for Research in Meteorology) and ONERA (The French aerospace lab) will use the version of the mesoscale atmospheric model MesoNH with Immersed Boundary Method (MesoNH-IBM) to investigate the coupling between meso- and microscale for an airport site (ONERA) and the urban site (CNRM). The grid nesting method implemented in MesoNH allows quantifying the interaction between meso- and microscale.
- The CEREA (Centre for Research on atmosphere and environment) has notable experience on atmospheric dispersion modelling and is developing the CFD Code_Saturne.
Objectives of postdoc or research engineer
Large Eddy Simulations at high resolution (around 10 m) will be conducted with the meso-scale atmospheric model Meso-NH over an airport. The aircraft emissions will be simulated as well as the pollutants chemistry and atmospheric dispersion for several large scale boundaries conditions (Ensemble simulations forcing) allowing to estimate the large scale influence on pollutants dispersion at the terminals and runways scale. These simulations will allow to develop model reduction.
Duration: 15 months
Skills: Fluid dynamics, atmospheric modelling
The position is already available, in Toulouse, France in the Department for Information Processing and System (DTIS).
