Analytic Study on the Thrust of Two-Dimensional Foil with Aileron in Wave Field
한국해양공학회지Numerous devices to reduce ship resistance have been suggested. One of them, a propagating hydrofoil in a wave field, can produce thrust and might be used to reduce the resistance of ships.

Numerical investigations of fluid structure coupling: oscillating hydrofoil
, 2008 This paper presents an investigation of the hydro elastic behavior of vibrating blades in hydraulic machines, which is of strong interest for turbo machinery applications. As a representative case study for vibrating blade in hydraulic machines, a NACA 0009 oscillating hydrofoil is considered.

Modelling of an oscillating hydrofoil, with a fluid-structure interaction approach
, 2020 As policies to fight greenhouse gas emissions are more and more demanding and as the global energy demand is constantly increasing, renewable energies are currently seen as an important contribution to the global energy mix. Among them, tidal energy has the advantage of a perfectly known and highly predictable intermittency. The present work is part of

, 2017 Flapping Foil is an ongoing development project at NTNU Technology Transfer working on a new way of propulsion for boats. Their goal is to eliminate two of the biggest issues with boats today, the low efficiency of boat propellers and the high friction created when moving in the water surface.
