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 …

We numerically investigate the dynamics of a self-propelled system that swims by using
intermittent jet propulsion through cyclic body deformations. Unlike existing studies, the …

Inspired by recent studies of a squid-like swimmer, we propose a three-dimensional jet
propulsion system composed of an empty chamber enclosed within a deformable body with …

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

By using an axisymmetric immersed-boundary model, we numerically investigate the thrust
generation of a deformable body via pulsed jetting. We focus on a single discharging …

The untethered swimming performance of a two-dimensional squid-inspired swimmer is
studied. Our model includes fully-coupled fluid-structure interaction and an idealized …

By using an axisymmetric immersed-boundary model, fluid dynamics of a cephalopod-
inspired propeller undergoing periodic inflation–deflation deformation in background flow is …

A squid-inspired jet propulsion system that indudes a deformable body and a nozzle exit
attached to it is numerically studied. By prescribing the body deformation during a single …

Pulsed-jets are commonly used for aquatic propulsion, such as squid and jellyfish
locomotion. The sudden ejection of a jet with each pulse engenders the formation of a vortex …

A three-dimensional pulsed-jet propulsion model consisting of a flexible body and a
steerable bent nozzle in tethered mode is presented and studied numerically. By prescribing …
