Numerical study on transient four-quadrant hydrodynamic performance of cycloidal propellers
TL;DR: In this paper , an efficient three-dimensional (3D) model with half-blades was established to investigate the transient four-quadrant hydrodynamics on blades under the circumferential motion of the steering center, and the results revealed that the variation of azimuth angle φ induces the rapid response of hydrodynamic loads, which directly affects the direction of ship motion.

Thrust scaling for a large-amplitude heaving and pitching foil with application to cycloidal propulsion
TL;DR: In this paper , a numerical solution procedure using the mesh-superposition approach, known as the Chimera method, together with the OpenFOAM toolbox environment is used to compute the forces generated by large amplitude heaving and pitching foil.

Drag reduction in fish-like locomotion
TL;DR: In this article, the authors present experimental force and power measurements demonstrating that the power required to propel an actively swimming, streamlined, fish-like body is significantly smaller than the power needed to tow the body straight and rigid at the same speed U.
Journal ArticleDOI
Review of experimental work in biomimetic foils
TL;DR: In this article, a review of the basic mechanisms of force production and flow manipulation in oscillating foils for underwater use is presented, focusing primarily on experimental studies on some of the, at least partially understood, mechanisms, which include the formation of streets of vortices around and behind two-and three-dimensional propulsive oscillating flapping foils.

Flume tank characterization of marine current turbine blade behaviour under current and wave loading
TL;DR: In this article, a series of flume tank measurements on strain gauged scaled turbine blades was performed to study the effects of both current and wave-current interactions on measured strains.
Journal ArticleDOI
Blockage effects on the hydrodynamic performance of a marine cross-flow turbine
TL;DR: Hydrodynamic efficiency, the ratio of useful power generated to overall power removed from the flow, is found to increase with blockage, which is consistent with the presence of a higher flow velocity through the core of the turbine at higher blockage ratios.

Survey of the mathematical theory of fish locomotion
TL;DR: An attempt is made to give a survey of the mathematical approach to the description of the swimming of fish, which gives insight in the fundamentals of the interaction of the body of the fish and the fluid.
