Coupling gas liquid compositional Darcy and free gas flows in collaboration with Nabil Birgle, Konstantin Brenner,
Yumeng Zhang and Laurent Trenty.
The objective of this project is to develop mathematical models, their discretizations and coupling algorithms
to simulate the coupling of a 3D gas liquid compositional Darcy flow with a compositional gas free flow.
Different models will be considered starting with a reduced model coupling a 3D flow in the Darcy region with
a 1D flow in the free flow region.
The targeted application is the drying by suction at the interface between the repository and the ventilation galery
in a nuclear waste deposit. It is the subject of the PhD of Yumeng Zhang funded by Andra and of the postdoctoral project of Nabil Birgle.
