Flexible slender structures are ubiquitous in biological systems and engineering
applications. Fluid-structure interaction (FSI) plays a key role in the dynamics of such …

Nearly all fish have flexible bodies that bend as a result of internal muscular forces and
external fluid forces that are dynamically coupled with the mechanical properties of the body …

Simple mechanical models emulating fish have been used recently to enable targeted study
of individual factors contributing to swimming locomotion without the confounding complexity …

An abundance of swimming animals have converged upon a common swimming strategy
using multiple propulsors coordinated as metachronal waves. The shared kinematics …

The vortex dynamics of thrust and lift generation for periodically plunging airfoils and finite
wings at low Reynolds numbers is reviewed. Effects of vortex lock-in phenomenon, leading …

The effects of passive, inertia-induced surface flexibility at the leading and trailing edges of
an oscillating airfoil energy harvester are investigated experimentally at reduced …

Unlike rigid rotors of drones, bird wings are composed of flexible feathers that can passively
deform while achieving remarkable aerodynamic robustness in response to wind gusts. In …

The versatility of fish to adapt to different swimming requirements is attributed to their
complex muscular system. Fish modulate their fin stiffness and shape for maximized …

Recent studies indicate that nature-inspired thrusters based on flexible oscillating foils show
enhanced propulsive performance. However, understanding the underlying physics of the …

In this research study, unsteady, viscous and turbulent fluid flow around a plunging hydrofoil
is simulated near the water free surface for different submergence depths and oscillation …
