Many animals in nature experience hydrodynamic benefits by swimming near the ground.
Inspired by near-ground swimmers, a flexible fin flapping near the ground was modeled in a …

A self-propelled flexible fin is subjected to perturbed flows produced by inanimate structures
or other moving organisms. An optimal flapping motion in unbounded fluids may not be …

The hydrodynamic performance of a self-propelled carangiform swimmer with a flexible
caudal fin in the absence of a free stream is numerically investigated, where the fin's …

Fish median fins are extremely diverse, but their function is not yet fully understood. Various
biological studies on fish and engineering studies on flapping foils have revealed that there …

Flexible tail fins are commonly found in undulatory swimmers which can propel freely in
omni-direction with flapping-wing-based propulsion. In this work, the hydrodynamic …

This paper examines the beneficial effects of the spanwise flexibility of the caudal fin for the
improvement of the swimming performance for small fishlike robots. A virtual swimmer is …

This paper aims to investigate the hydrodynamics of a three-dimensional (3-D) flapping
caudal fin in ground effect by using numerical simulation and experimental test. Three types …

Studies of aquatic locomotion typically assume that organisms move through unbounded
fluid. However, benthic fishes swim close to the substrate and will experience significant …

We carry out fluid–structure interaction simulations of self-propelled virtual swimmers to
investigate the effects of body shape (form) and kinematics on the hydrodynamics of …

Many aquatic organisms swim by means of an undulating fin. These undulations often form
a single wave travelling from one end of the fin to the other. However, when these aquatic …
