Fluid–structure coupling for an oscillating hydrofoil [PDF]
Journal of Fluids and Structures, 2010 Abstract Fluid-structure investigations in hydraulic machines using coupled simulations are particularly time-consuming. In this study, an alternative method is presented that linearizes the hydrodynamic load of a rigid, oscillating hydrofoil. The hydrofoil, which is surrounded by incompressible, turbulent flow, is modeled with forced and free ...

Oscillating Hydrofoil Propulsion for Human-Powered Watercraft Applications [PDF]
, 2013 Unlike conventional propellers, flapping wings may generate large amplitude oscillating forces, which can make them difficult to incorporate into a craft design. This is particularly true for a single, vertically oscillating hydrofoil, as part of a surface water craft where the cyclic lift of the hydrofoil disrupts the craft stability.

Fish-Inspired Hydrodynamic Study of Stationary, Undulating, and Oscillating Hydrofoils
, 2022 A fish-inspired research, on flow across a hydrofoil that is stationary or mimicking various types of fish-inspired swimming, can reveal efficient flow mechanisms that can lead to a novel design and development of autonomous underwater vehicles (AUVs) or energy extraction devices. The present thesis starts with various flow transitions in the wake of a

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 ...
