Abstract

Freely falling disks follow a rich variety of paths, from steady descent to fluttering and tumbling. We examine how porosity reshapes these regimes. The porous disk is modelled by a homogenized interface whose permeability and slip coefficients are computed once and for all from unit-cell Stokes problems. This links the pore microstructure to the macroscopic flow without resolving the full-scale geometry.

White, wavy, hair-like strands flow in parallel curves within a circular frame on a black background, creating an abstract, textured pattern.
