The fluid dynamics of flapping foils are reviewed in this article. A very wide range of
researches are conducted for the two-dimensional flapping foil which has a relatively simple …

In the field of renewable energy, high-altitude wind energy emerges as a promising source,
particularly at altitudes (> 300 m) where conventional wind turbines cannot reach. Currently …

The work in this paper focuses on the examination of the effect of variable stiffness
distributions on the kinematics and propulsion performance of a tuna-like swimmer. This is …

The energy harvesting potential of flexible structures (eg flags) made of piezoelectric
materials has drawn rapidly increasing attention in recent years. In this work, we numerically …

Energy harvesting from flow induced vibrations (FIV) in flexible bodies offer opportunities for
power generation in biomimicking robotic devices and is an active area of research. The …

Batoid fishes have agile maneuverability by flapping pectoral fins with complex undulatory
waves. To reveal the effect of fin motion kinematics on torque production, we numerically …

Research on fish locomotion has made extensive progress towards a better understanding
of how fish control their flexible body and fin for propulsion and maneuvering. Although the …

In this paper, we numerically investigate the effects of time-varying bending stiffness on the
propulsion performance of a flapping foil using a fully coupled fluid-structure interaction …

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 …

As a promising form of oscillating hydrofoil propulsion, self-pitching flapping foil (SPFF) has
been widely used in ocean engineering applications such as ships, underwater vehicles …
