Main project: An hybrid multiscale model for immersed granular flows
Funding: FRIA
Supervisor(s): Vincent Legat

The goal of his thesis is to develop an hybrid multiscale model for immersed granular flows. On one hand, the motion of the grains is obtained by a discrete element method at the granular scale. On the other hand, modified Navier-Stokes equations for porous media are solved to compute the mixture flow using a finite element method at a greater scale than the grains scale. Such a model can be used to represent highly inhomogeneous immersed granular flows going from pure fluid to porous media. The discrete representation of the grains will provide the possibility to discribe accurately the physics of the grains and their interaction with complex geometries while the continuous representation of the mixture will induce a reduced computational time.
