Optimal stroke patterns for Purcell's three-link swimmer.
نویسندگان
چکیده
Stroke patterns for Purcell's three-link swimmer are optimized. We model the swimmer as a jointed chain of three slender rods moving in an inertialess flow. The swimmer is optimized for efficiency and speed. We were able to attain swimmer designs significantly more efficient than those previously suggested by authors who only consider geometric design rather than kinematic criteria. The influence of slenderness on optimality is considered as well.

Comment on "optimal stroke patterns for Purcell's three-link swimmer".
In the letter " Optimal strokes patterns for Purcell's three-linked swimmer " , Tam and Hosoi [2] describe the optimization of the distance covered in one stroke, and the swimming efficiency of Purcell's three linked swimmer. They allow for optimizing the geometry of the swimmer—the ratio between the links—and choosing a stroke. The calculations are made in the framework Cox slender body theory...
متن کاملRehinging biflagellar locomotion in a viscous fluid.
A means of swimming in a viscous fluid is presented, in which a swimmer with only two links rotates around a joint and then rehinges in a periodic fashion in what is here termed rehinging locomotion. This two-link rigid swimmer is shown to locomote with an efficiency similar to that of Purcell's well-studied three-link swimmer, but with a simpler morphology. The hydrodynamically optimal stroke ...
متن کاملOn self-propulsion of micro-machines at low Reynolds number: Purcell's three-link swimmer
Using slender-body hydrodynamics in the inertialess limit, we examine the motion of Purcell’s swimmer, a planar, fore–aft-symmetric three-link flagellum or propulsive mechanism that translates by alternately moving its front and rear segments. Purcell (1976) concluded via symmetry arguments that the net displacement of such a swimmer must follow a straight line, but the direction and other deta...
متن کاملGeometric Controllability of The Purcell's Swimmer and its Symmetrized Cousin
We analyse weak and strong controllability notions for the locomotion of the 3-link Purcell’s swimmer, the simplest possible swimmer at low Reynolds number from a geometric framework. After revisiting a purely kinematic form of the equations, we apply an extension of Chow’s theorem to analyze controllability in the strong and weak sense. Further, the connection form for the symmetric version of...
متن کاملNotes on geometry of locomotion of 3-dimensional version of the Purcell's swimmer
We analyse the geometry of locomotion of 3-link mechanism inspired from the Purcell’s swimmer at low Reynolds number, the simplest possible swimmer conceptualized in [1]. The literature has extensively analyzed the problem of plananr locomotion of the Purcell’s swimmer [2], [3], [4], [5]. [6] analyzes its locomotion problem in geometric framework, again for the planar case. The condition of bei...
