Numerical Analysis of Hydrodynamics for Bionic Oscillating Hydrofoil Based on Panel Method [PDF]
Applied Bionics and Biomechanics, 2016 The kinematics model based on the Slender-Body theory is proposed from the bionic movement of real fish. The Panel method is applied to the hydrodynamic performance analysis innovatively, with the Gauss-Seidel method to solve the Navier-Stokes equations ...

Various Wavy Leading-Edge Protuberance on Oscillating Hydrofoil Power Performance [PDF]
Journal of Applied Fluid Mechanics, 2023 This paper is presented to compare various wavy leading-edge protuberances on oscillating hydrofoil performance and power efficiency. The unsteady turbulent 3D flow simulations were carried out by using the StarCCM+ software.

An inertial mechanism behind dynamic station holding by fish swinging in a vortex street [PDF]
Scientific Reports, 2022 Many aquatic and aerial animal species are known to utilise their surrounding flow field and/or the induced flow field of a neighbour to reduce their physical exertion, however, the mechanism by which such benefits are obtained has remained elusive.

Hydrodynamic Study of Flow-Channel and Wall-Effect Characteristics in an Oscillating Hydrofoil Biomimetic Pumping Device [PDF]
BiomimeticsTo clarify how flow-channel configuration and wall spacing govern the hydrodynamic performance of an oscillating-hydrofoil biomimetic pumping device, this study conducted a systematic numerical investigation under confined-flow conditions. Using a finite-

Effects of non-sinusoidal pitching motion on the propulsion performance of an oscillating foil. [PDF]
PLoS ONE, 2019 Numerical simulations have been used in this paper to study the propulsion device of a wave glider based on an oscillating hydrofoil, in which the profile of the pitching and heaving motion have been prescribed for the sake of simplicity.

Comparing Models of Lateral Station-Keeping for Pitching Hydrofoils [PDF]
Biomimetics, 2019 Fish must maneuver laterally to maintain their position in schools or near solid boundaries. Unsteady hydrodynamic models, such as the Theodorsen and Garrick models, predict forces on tethered oscillating hydrofoils aligned with the incoming flow.

Undulatory Propulsion at Milliscale on Water Surface. [PDF]
Adv Sci (Weinh)The water‐surface propulsion of an undulatory swimmer stems from the complex interplay of various forces that are generated by the body's waveform and the waves at the water‐air interface. Adjusting the material and dimensions of the body, along with the excitation manner of the head, allows for tuning of the swimmer's waveform that is crucial for ...
