Title: Multi-scale modeling of clogging in permeable pavements using CFD–DEM coupling

The postdoctoral researcher will be responsible for developing a multi-scale numerical approach dedicated to modeling the evolution of permeability in permeable and draining pavement layers, in relation to progressive clogging mechanisms induced by cohesive and non-cohesive sediments. This work is part of the ANR-I OpenPav project.

The research will focus on the influence of:

the properties of the pore network,

the grain size distribution of the materials,

the nature of the sediments,

deposition mechanisms, arching effects, and accumulation,

on the kinetics of hydraulic conductivity loss. Special attention will be given to resolved and unresolved CFD–DEM coupling.

Main activities:

Develop numerical models to study the permeability of draining layers.

Implement resolved CFD–DEM ...
