*Hosting Institute
The University of Rouen Normandy (https://www.univ-rouen.fr/), with its strong
multidisciplinary identity, is a major player in training and research in 
Normandy region and in France. It pays particular attention to overcome the 
challenges of higher education and contribute to the overall economic and social 
development of its territory. Created in 1967, CORIA, “Complexe de Recherche 
Interprofessionnel en Aérothermochimie" (https://www.coria.fr/en/the-lab/), is a 
Joint Research Unit (UMR 6614) CNRS and the University of Rouen Normandy.

*Research Context 
This research internship is a part of a large project “HÉLIOS” entitled “De la 
caractérisation spatiale, sanitaire et sociale des pHÉnomènes d'îLots de chaleur 
urbaIns à l'exploration et l'évaluation de solutiOns d'adaptation fondéeS sur la 
nature” by 5 lcoal region communities (Le Havre, Métropole Rouen Normandie, 
Mantes-la-Jolie, Communauté d'Agglomération de Cergy-Pontoise, Argenteuil) in 
collaboration with CORIA Lab, other labs and the T.URN institute 
(https://www.univ-rouen.fr/actualites/decouvrez-linstitut-t-urn/). 
This internship is also in a global context of developing a multi-risk platform 
in Normandy region in France (e.g. for floods, fires and particles dispersion, 
air pollution dispersion, among others). One of the missions is to predict 
accurately the local urban heat island effects and local heat waves at the scale 
of the city.

*Objective
The main objective is to develop, implement and validate a mesoscale model in CFD to 
take into account the urban trees effect on the outdoor microclimate by coupling a 
canopy energy balance (CEB) models. This will allow to investigate how local trees in 
the métropole region can affect outdoor microclimate under different wind speeds, 
air conditions, solar radiation and stomatal resistance.
The major 3 work packages in this internship are the following:
1- Take into hands the CFD code OpenFOAM® and implement a new CEB model
2- Define and solve a bench 3D CFD case to validate the newly implemented CEB model 
3- Define and solve a 3D CFD case of the métropole that will investigate/predict 
   the effects of different scenarios of local wind speeds, air conditions, solar 
   radiation and stomatal resistance.

*Required Profile
Scientific Background: Student currently in Master-2 (M.Sc.) in the fields of computational 
fluid dynamics, aerodynamics, turbulence, heat and mass transfer. 
Experience within OpenFOAM® in particular would be a plus (https://www.openfoam.com/).

*Skills: Taste for modeling and numerical simulation in CFD, in-depth notions in fluid mechanics 
and turbulence, and aerodynamics in presence of obstacles and immersed objects. Interest in 
high performance and parallel computing within CFD. Good taste for a teamwork and a good level of 
Scientific English, speaking, reading and writing.
