Description
Isabell Noichl and Clarissa Schönecker report laboratory work from 2026 on small spheres settling through fluid close to a solid wall. They tracked soft and rigid particles starting from rest inside a narrow channel, at very low particle Reynolds numbers.
Early in each fall the particles drifted toward the wall, a pull the authors link to fluid inertia. At somewhat higher flow speeds rigid spheres later moved away, matching older lift models, while slower runs stayed unsteady. Computer flow simulations backed the readings. Their regime map may help interpret how deformable microplastics move near boundaries in water treatment settings.
