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

Biological flows in swimming and flying bio-locomotion usually involve intricate flexible or
rigid structures that undergo large deformations and displacements, as well as rich …

The immersed boundary method is a methodology for dealing with boundary conditions at
fluid–fluid and fluid–solid interfaces. The immersed boundary method has been attracting …

Pulsatile jet propulsion is a common swimming mode used by a diverse array of aquatic taxa
from chordates to cnidarians. This mode of locomotion has interested both biologists and …

Increasing frequency of native jellyfish proliferations and massive appearance of non-
indigenous jellyfish species recently concur to impact Mediterranean coastal ecosystems …

An inflation–deflation propulsion system inspired by the jet propulsion mechanism of squids
and other cephalopods is proposed. The two-dimensional squid-like swimmer has a flexible …

The propulsive performance and vortex dynamics of a two-dimensional model for the
jellyfish-like propulsion with burst-and-coast strategy are investigated using a penalty …

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 …

Colonial physonect siphonophores swim via laterally distributed multijet propulsion at
intermediate Reynolds numbers (Re's) on the orders of 1–1000. Here, a computational fluid …

We propose a novel underwater propulsion system inspired by the jet-propelled locomotion
mechanism of squids and other cephalopods. A two-dimensional nonaxisymmetric fluid …
