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.

A Preliminary Experimental Study of Vertical Hydrofoils of Low Aspect Ratio Piercing a Water Surface [PDF]
, 1954 Most types of problems which arise in connection with the use of a hydrofoil operating in water can be solved simply by treating it as an airfoil operating in air.

Experiments in carangiform robotic fish locomotion [PDF]
, 2000 This paper studies a form of robotic fish movement that is analogous to the carangiform style of swimming seen in nature. We propose a simple quasi-steady fluid flow model for predicting the thrust generated by the flapping tail.

Experimental Study of Cavitating Hydrofoils in Cascade [PDF]
, 1968 Liquid filled hydraulic systems often operate in such a way that cavitation may take place in one or more of the components of the system. Most often the cavitation will take place in a pump or a turbine as the liquid velocity there is usually greatest ...

Hydroacoustic Testing of a NACA-66 (MOD) Hydrofoil in the GALCIT High Speed Water Tunnel [PDF]
, 1991 The work described in this report represents a primarily exploratory effort to assess the feasibility of performing accurate hydroacoustic measurements at high signal-to-noise ratios, in the GALCIT High Speed Water Tunnel (HSWT), hereafter referred to ...

Vortex-enhanced propulsion [PDF]
, 2011 It has been previously suggested that the generation of coherent vortical structures in the near-wake of a self-propelled vehicle can improve its propulsive efficiency by manipulating the local pressure field and entrainment kinematics.

Shock Waves and Noise in the Collapse of a Cloud of Cavitation Bubbles [PDF]
, 1995 Calculations of the collapse dynamics of a cloud of cavitation bubbles confirm the speculations of Morch and his co-workers and demonstrate that collapse occurs as a result of the inward propagation of a shock wave which grows rapidly in magnitude ...
