WebDec 4, 2024 · The wake dynamics is studied after quantitative analysis of particle image velocimetry data, and it is linked to the momentum transfer generated by the foil. ... WebMar 22, 2024 · Abstract. Natural and artificial flapping wing flyers generally do not exhibit chaos or aperiodic dynamic modes, though several experimental and numerical studies …
WebJun 26, 2012 · Flexible flapping foils shed a vortex wake that can be compared to the wake generated by freely swimming fishes. Figure 7 shows the three-dimensional wake behind a flexible foil (like that of a bluegill sunfish, Lepomis macrochirus) of the same flexural stiffness as the foils shown in Fig. 6. WebDec 5, 2024 · In-phase and anti-phase synchronization of neighboring swimmers is examined experimentally using two self-propelled independent flexible foils swimming side-by-side in a water tank. The foils are actuated by pitching oscillations at one extremity—the head of the swimmers—and the flow engendered by their …
WebNov 13, 2015 · Abstract. This work presents an autonomous soft-bodied robotic fish that is hydraulically actuated and capable of sustained swimming in three dimensions. The design of a fish-like soft body has been extended to deform under hydraulic instead of pneumatic power. Moreover, a new closed-circuit drive system that uses water as a transmission … WebJan 5, 2015 · The propulsive dynamics of a flexible undulating foil in a self-propelled swimming configuration near a wall is studied experimentally. Measurements of the swimming speed and the propulsive force are presented, together with image acquisition of the kinematics of the foil and particle image velocimetry (PIV) in its wake.
