文摘

Distinct flow patterns during one and two ellipses settling are summarized. Rotation speeds up before resonance and settlement slows down with frequency. The turning couple with lateral displacement in oscillatory flow is revealed. The Magnus lift influences the balance between walls and particles interplay.
