Observations of Oscillating Cavitation on a Flat Plate Hydrofoil.

JSME International Journal Series B, 1999
An experimental investigation was made to clarify the characteristics of oscillating cavitation on a flat plate hydrofoil in a water tunnel. Dynamic the behavior of oscillating cavitation is discussed from the unsteady pressure measurements at the upstream of the blade and the visual observations of cavitation phenomena using high-speed video ...

Research on the Influence of Hydrofoil Propulsive Parameters on Propulsion Efficiency

Journal of Marine Science and Engineering
Oscillating hydrofoils can be used to simplify the study of the swinging caudal fin propulsive mode of fish, where the motion parameters have a direct impact on the hydrodynamic performance and propulsive efficiency. In this study, numerical calculations

Multimodal Locomotion of Soft Robots

Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.
This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

Untangling sedimentation processes in a deep fjord lake in Labrador: A high‐resolution archive of past environment dynamics at Grand Lake

The Depositional Record, Volume 11, Issue 5, Page 1259-1284, November 2025.
Sedimentological and geochemical characteristics are used to reconstruct sedimentation dynamics and erosional processes. Several rapidly deposited layers are characterised over changing depositional environments during the Late Holocene, from a phase when the lake was connected to the sea to a more stable state conducive to varve formation.

Numerical Study on Hydrodynamic Performance of a Pitching Hydrofoil with Chordwise and Spanwise Deformation

Journal of Marine Science and Engineering
The hydrofoil plays a crucial role in tidal current energy (TCE) devices, such as horizontal-axis turbines (HATs), vertical-axis turbines (VATs), and oscillating hydrofoils.

Flow Memory Effect on Open‐Frame Remotely Operated Vehicle Motion

Journal of Field Robotics, Volume 42, Issue 6, Page 2611-2638, September 2025.
ABSTRACT The flow memory effect is a kind of viscous force caused by acceleration between continuous phases and underwater vehicles and the development of the boundary layer near the interfacial surface. This paper establishes a 6‐degrees‐of‐freedom unsteady equation of motion describing the flow memory effect on viscous hydrodynamic loads.

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 additionally, to evaluate the flexible deformation of fish in swimming accurately when satisfying ...

Research on swimming hydrodynamics based on a three‐dimensional high‐precision fish model

River, Volume 4, Issue 3, Page 341-350, August 2025.
Abstract Fish swimming hydrodynamics serves as a critical foundation for aquatic ecological conservation, with recent research extending from 2D to 3D perspectives. This study employs 3D high‐fidelity modeling with dynamic mesh technology to investigate how cylindrical obstacles at varying positions affect Carassius auratus locomotion. Analysis of nine

Backward swimming in elongated‐bodied abyssal demersal fishes: Synaphobranchidae, Macrouridae, and Ophidiidae

Journal of Fish Biology, Volume 107, Issue 1, Page 52-62, July 2025.
Abstract The deep‐sea demersal fish fauna is characterized by a prevalence of elongated‐body forms with long tapering tails. Using baited camera landers at depths of 4500–6300 m in the Pacific Ocean, we observed multiple instances of backward swimming using reverse undulation of the slender body in four species: the cutthroat eel Ilyophis robinsae ...

Lacustrine and fan‐delta sediments in syn‐rift lake basins

The Depositional Record, Volume 11, Issue 3, Page 857-892, June 2025.
A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...
