Nature presents a variety of propulsion, maneuvering, and stabilization mechanisms which
can be inspired to design and construction of manmade vehicles and the devices involved in …

Heaving airfoils can provide invaluable physical insight regarding the flap** flight of birds
and insects. We examine the thrust-generation mechanism of oscillating foils, by coupling …

The wake field of the flexible oscillating caudal fin is investigated using the Digital Particle
Image Velocity (DPIV) system. The distributions of the vorticity with different Strouhal …

A fish robot with image sensors is useful to seek disaster victims in flood areas. In order to
perform rescue operation for long time, the method of supplying electric power is important …

Thunniform propulsion is considered a case study in convergent evolution. Independently
derived at least four times, it is characterized by uniquely high lift-based thrust and efficient …

The flow around an unsteady hydrofoil, undergoing simultaneous heaving and pitching
motions which mimic the tail motions of carangiform fish (such as tuna), was investigated …

Applying compliant-wall coatings to otherwise rigid surfaces can delay the onset of laminar-
turbulent transition and offer marked reductions in skin-friction drag and energy …

Due to the rising demand for low-cost clean energy, the development of efficient wind and
water energy-generating systems is one of the major goals of this century. A novel approach …

Thunniform propulsion is considered a case study in convergent evolution. Independently
derived at least four times (whales, lamnid sharks, tunas and ichthyosaurs) it is …
