We study a linear inviscid model of a passively flexible swimmer, calculating its propulsive performance, eigenvalues and eigenfunctions with an eye towards clarifying the relationship between efficiency and resonance. The frequencies of actuation and stiffness ratios we consider span a large range, while the mass ratio is mostly fixed to a low value representative of swimmers. We present results showing how the trailing edge deflection, thrust coefficient, power coefficient and efficiency vary… 

Distributed flexibility in inertial swimmers

Results are presented showing how the trailing edge deflection, thrust coefficient, power coefficient and efficiency vary with frequency, mean stiffness and stiffness distribution, and speculate on the effects of a finite Reynolds number in the form of streamwise drag.

Analytical results for the propulsion performance of a flexible foil with prescribed pitching and heaving motions and passive small deflection

Connections between resonance and nonlinearity in swimming performance of a flexible heaving plate

We investigate the role of resonance in finite-amplitude swimming of a flexible flat plate in a viscous fluid. The role of resonance in performance remains unclear for two reasons: (i) a lack of

Thrust generation by a heaving flexible foil: Resonance, nonlinearities, and optimality

Flexibility of marine animal fins has been thought to enhance swimming performance. However, despite numerous experimental and numerical studies on flapping flexible foils, there is still no clear

Resonance and propulsion performance of a heaving flexible wing

The influence of the bending rigidity of a flexible heaving wing on its propulsive performance in a two-dimensional imposed parallel flow is investigated in the inviscid limit. Potential flow theory

Rather than resonance, flapping wing flyers may play on aerodynamics to improve performance

It is shown that flapping flyers optimize their performance not by especially looking for resonance to achieve larger flapping amplitudes with less effort, but by tuning the temporal evolution of the wing shape to optimize the aerodynamics.

Effects of flexibility on the aerodynamic performance of flapping wings

It seems that the maximum propulsive force is obtained when flapped near the resonance, whereas the optimal propulsive efficiency is reached when flapping at about half of the natural frequency; both are supported by the reported studies.

Maximizing the efficiency of a flexible propulsor using experimental optimization

Experimental gradient-based optimization is used to maximize the propulsive efficiency of a heaving and pitching flexible panel and the multi-dimensionality and multi-modality of the efficiency response demonstrate that experimental optimization is well-suited for the design of flexible underwater propulsors.

Influence of flexibility on the aerodynamic performance of a hovering wing

It was found that flexibility can enhance aerodynamic performance and that the best performance is realized when the wing is excited by a non-linear resonance at 1/3 of the natural frequency, which points to the importance of considering non- linear resonances for enhancing aerodynamics performance.
