Transport of ellipsoidal microplastic particles in a 3D lid-driven cavity under size and aspect ratio variation
作者：
Highlights：
• Eulerian–Lagrangian system for the particle and hydrodynamics and a one-way coupling.
• Quasi-steady state approximations of particle velocity under sufficiently small particle sizes.
• Sedimentation depending on the particle’s initial position, aspect ratio, and size.
• The cavity base and vorticity-dominating regions as the deposition hotspots.
• Speed of tumbling and spinning motion for various aspect ratios.
