Anomalous hydrodynamic drafting of interacting flapping flags.
In aggregates of objects moving through a fluid, bodies downstream of a leader generally experience reduced drag force. This conventional drafting holds for objects of fixed shape, but interactions of deformable bodies in a flow are poorly understood, as in schools of fish. In our experiments on "schooling" flapping flags, we find that it is the leader of a group who enjoys a significant drag r...
متن کاملFlow energy harvesting with piezoelectric flags
In this article, energy harvesting with a fluttering cantilevered plate covered by piezoelectric patches in an axial flow is adressed. A theoretical model is presented which is then discretized and numerically integrated to perform a parametric study of the energy harvesting efficiency of the system. When one, two or three piezoelectric patches cover the plate, the optimal distributions of the ...
متن کاملComments on ”Anomalous Hydrodynamic Drafting of Interacting Flapping Flags”
We make remarks on Ristroph and Zhang’s [Phys. Rev. Lett. 101, 194502 (2008)] paper. We argue especially that due to the interferences the calibration procedures in [1] were not complete and this will induce some measurements’ error. Ristroph and Zhang just presented an interesting observation about the inverted drag relationship for 6 tandem flags where inverted drafting directly suggests hydr...
متن کاملApplication of the airflow control by electro-hydrodynamic actuator
The technique used to control the airflow is based on the electro-hydrodynamic actuator which is also called plasma actuator. This actuator ensures the airflow control thanks to the electric wind created by the electrical corona discharge. This ionic wind is developed at the profile surface tangential to the initial free airflow so that it has a significant effect on the boundary layer flow. Th...
متن کاملHydrodynamic synchronization of flagellar oscillators
In this review, we highlight the physics of synchronization in collections of beating cilia and flagella. We survey the theory synchronization in collections of noisy oscillators. This framework is applied to flagellar synchronization by hydrodynamic interactions. The time-reversibility of hydrodynamics at low Reynolds numbers prompts swimming strokes that break symmetry to facilitate hydrodyna...
