Orientation dynamics of nonspherical particles under surface gravity waves
AI summary Read the abstract
This experimental study found that non-spherical particles (like many microplastic fragments) orient themselves in specific ways when exposed to surface ocean waves, affecting how they move and sink. These orientation effects are not captured in simple spherical particle models, suggesting current microplastic transport predictions may be inaccurate.
