Significant progress has been made in understanding some of the basic mechanisms of
force production and flow manipulation in oscillating foils for underwater use. Biomimetic …

We consider observations and data from live fish and cetaceans, as well as data from
engineered flap** foils and fishlike robots, and compare them against fluid mechanics …

We study experimentally the vortex streets produced by a flap** foil in a hydrodynamic
tunnel, using two-dimensional particle image velocimetry. An analysis in terms of a flap** …

Experiments are reported on the hydrodynamic performance of a flexible fin. The fin
replicates some features of the pectoral fin of a batoid fish (such as a ray or skate) in that it is …

The effects of changing Strouhal number on the three-dimensional wake produced by a
rigid, bioinspired trapezoidal pitching panel are analyzed through the use of stereoscopic …

We have conducted three-dimensional (3D) direct numerical simulations to analyze vortex-
shedding modes past vertically arranged, side-by-side 3D pitching plates, considering cases …

The evolution of wake structures behind thin pitching panels at Reynolds number 1000 is
studied numerically for a wide range of aspect ratios (0. 54≤ AR≤ 16). At the maximum …

A potential flow solver (BEM) is used to simulate a porpoising foil in order to compare the
hydrodynamic performance of the biomimetic propulsion device with a conventional …

This paper describes work done in the modeling and control of a low speed underwater
vehicle that uses paddles instead of thrusters to move in the water. A review of previously …

The role of the chordwise flexural stiffness in a rectangular foil undergoing pure pitching has
been investigated experimentally. Digital Particle Image Velocimetry (DPIV) and load …
