WebApr 9, 2024 · This paper studies the displacement and efficiency of a Purcell’s three-link microswimmer in low Reynolds number regime, capable of moving by the implementation of a motion primitive or gait. An optimization is accomplished attending to the geometry of the swimmer and the motion primitives, considering the shape of the gait and its amplitude.

WebJul 10, 2024 · Control of swimmers using two-way coupling and RL have been demonstrated with linked-spheres at low Reynolds numbers [160] and for artificial fish in macro-scales [161]. WebDec 2, 2024 · Because of their small scale, cilia operate at low Reynolds numbers, where nonreciprocal motions are necessary to induce a net flow, as pointed out by Purcell’s scallop theorem . At low Reynolds numbers ( Re ≪ 1), viscous forces dominate inertial effects, and flow interactions can be described using Stokes equation, which is time reversible.

In physics, the scallop theorem states that a swimmer that exhibits time-symmetric motion cannot achieve net displacement in a low-Reynolds number Newtonian fluid environment, i.e. a fluid that is highly viscous. Such a swimmer deforms its body into a particular shape through a sequence of motions and then reverts to the original shape by going through the sequence in reverse. Th…
