Parking 3-sphere swimmer: II. The long-arm asymptotic regime

摘要

The paper carries on our previous investigations on the complementary version of Purcell's rotator (sPr(3)): a low-Reynolds-number swimmer composed of three balls of equal radii. In the asymptotic regime of very long arms, the Stokes-induced governing dynamics is derived, and then experimented in the context of energy-minimizing self-propulsion characterized in the first part of the paper.
