Durée : 18 months
3D CFD simulations are up to now rarely used in air quality, although they may allow to characterize the heterogeneities of pollutant concentrations in cities at a district or neighborhood scale. We propose a research program of 18 months for a post-doctoral trainee. The trainee will participate to an international benchmark on air-quality modelling to compare 3D CFD LES simulations to measurements performed in the city of Paris. He will also realise the LES simulations with our 3D CFD platform code_saturne (https://www.code-saturne.org) associated with SSH-aerosol (https://sshaerosol.wordpress.com/) to treat the physico chemical transformation of gas and aerosols during atmospheric transport. At last, he will be able to compare the results of his simulations with respect to in-situ atmospheric measures giving access to the local chemical composition in the streets of Paris with experimental setups, and to the results of other 3D models. This comparison may allow to characterize how the heterogeneities differ depending on pollutants and open up the way to modelling improvements of urban air quality. The trainee will be part of the air quality modelling team, led by Research Director Karine Sartelet, of ENPC, team in which the development and validation of SSH-aerosol is conducted. He will also be associated to the team led by Dr Martin Ferrand of EDF R&D, on 3D modelling of the atmospheric layer with code_saturne. Both competences will allow him to develop fully coupled simulations using both tools.
