Optimal Energy Harvesting from Vortex-Induced Vibrations of Cables
G. O. Antoine, E. de Langre, S. Michelin
Vortex-induced vibrations (VIV) of flexible cables are an example of flow-induced vibrations that can act as energy harvesting systems by converting energy associated with the spon…
Edge flutter of long beams under follower loads
Emmanuel de Langre, Olivier Doaré
The linear instability of a beam tensioned by its own weight is considered. It is shown that for long beams, in the sense of an adequate dimensionless parameter, the characteristic…
A space-averaged model of branched structures
Diego Lopez, Emmanuel de Langre, Sébastien Michelin
Many biological systems and artificial structures are ramified, and present a high geometric complexity. In this work, we propose a space-averaged model of branched systems for con…
On the efficiency of energy harvesting using vortex-induced vibrations of cables
Clement Grouthier, Sebastien Michelin, Remi Bourguet +2
Many technologies based on fluid-structure interaction mechanisms are being developed to harvest energy from geophysical flows. The velocity of such flows is low, and so is their e…
Drag Reduction, from Bending to Pruning
Diego Lopez, Christophe Eloy, Sébastien Michelin +1
Most plants and benthic organisms have evolved efficient reconfiguration mechanisms to resist flow-induced loads. These mechanisms can be divided into bending, in which plants redu…
Self-similar vortex-induced vibrations of a hanging string
Clement Grouthier, Sebastien Michelin, Yahya Modarres-Sadeghi +1
An experimental analysis of the vortex-induced vibrations of a hanging string with variable tension along its length is presented in this paper. It is shown that standing waves dev…
The effect of non-uniform damping on flutter in axial flow and energy harvesting strategies
Kiran Singh, Sebastien Michelin, Emmanuel de Langre
The problem of energy harvesting from flutter instabilities in flexible slender structures in axial flows is considered. In a recent study, we used a reduced order theoretical mode…
Energy harvesting using vortex-induced vibrations of tensioned cables
Clement Grouthier, Sebastien Michelin, Emmanuel de Langre
The development of energy harvesting systems based on fluid/structure interactions is part of the global search for innovative tools to produce renewable energy. In this paper, the…
Damping by branching: a bioinspiration from trees
Benoit Theckes, Emmanuel de Langre, Xavier Boutillon
Man-made slender structures are known to be sensitive to high levels of vibration, due to their flexibility, which often cause irreversible damage. In nature, trees repeatedly endu…
Flow-induced pruning of branched systems and brittle reconfiguration
Diego Lopez, Sebastien Michelin, Emmanuel de Langre
Whereas most plants are flexible structures that undergo large deformations under flow, another process can occur when the plant is broken by heavy fluid-loading. We investigate he…
Simple modeling of self-oscillation in Nano-electro-mechanical systems
A. Lazarus, T. Barois, S. Perisanu +6
We present here a simple analytical model for self-oscillations in nano-electro-mechanical systems. We show that a field emission self-oscillator can be described by a lumped elect…
