Expérimental et théorique
From hairs on our skin to the microscopic cilia inside our respiratory tract, large aggregates of thin deformable structures in contact with fluids are ubiquitous. In this project, using model experiments we aim at understanding how a channel filled with deformable hairs affect fluid flow and can trap small particles carried by the flow. These hairy channels constitute a very peculiar porous media where the pore size can vary as the hairs are bent by the fluid flow which should impact the clogging process.
