Numerical Simulation on Vortex Shedding from a Hydrofoil in Steady Flow
Journal of Marine Science and Engineering, 2020 This paper presents a numerical modeling procedure for the idealization of vortex shedding effects in the wake flow field of a NACA0009 hydrofoil. During the simulation, the lift and drag acting on the hydrofoil were monitored, and the vortex-shedding ...

Hydrofoils and Hydrofoil Craft [PDF]
Annual Review of Fluid Mechanics, 1973 At the present time several hundred hydrofoilcraft are in service throughout the world. The upsurge in the use of these craft did not really begin until the late 1950s, although fascination with the idea of supporting small boats with underwater wings dates well back into the nineteenth century.
