Role of Shape and Kinematics in the Hydrodynamics of a Fish-like Oscillating Hydrofoil
Journal of Marine Science and Engineering, 2023 In the present two-dimensional numerical study, we investigate the roles of geometrical parameters of a hydrofoil (shape/curvature of the leading and trailing edges and thickness) and kinematic parameters (phase difference between heave and pitch (ϕ)) on

An experimental study of boundary-layer transition induced vibrations on a hydrofoil [PDF]
, 2010 This paper aims at characterizing experimentally laminar to turbulent transition induced vibrations. Here, the transition is known to be triggered by a Laminar Separation Bubble that results from a laminar separation of the boundary-layer flow on a ...

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 ...
