Flow-Oscillating Structure Interactions and the Applications to Propulsion and Energy Harvest

Abstract

This manuscript reviews the advance in understanding of the mechanisms of the interactions between oscillating structures and fluid flows. Many analytical, numerical and experimental approaches to model and to identify the non-stationary, nonlinear interactions between fluid flows and oscillating structures are summarized. The applications of fluid flow-oscillating structure interaction to propulsion and energy harvest are discussed. The issue of the establishment of generalized, parametric, reduced-order models is discussed with an aim at illustrating the perspectives for improving the correlation between test data and physics-based modeling.

Transverse galloping of two-dimensional bodies having a rhombic cross-section

“…A large number of papers has been published where the suitability of some specific mechanisms to efficiently harvest electric energy through different energy converters (piezoelectric, electromagnetic, etc.) are considered [7][8][9]. Therefore, a considerable effort is being devoted to analyze this wind-induced vibration and develop simple theories to evaluate the energy-harvesting capabilities of twodimensional bluff bodies.…”

Flutter-driven triboelectrification for harvesting wind energy

“…Recently, flow-induced vibration of flexible structures has been suggested as an alternative to overcome the drawbacks of wind-turbine-based wind energy generator including structural complexity, the large volume and weight, high cost of manufacturing and installation, low efficiency and noise. Most research in this area is focused on piezoelectric materials [4][5][6][7] such as lead zirconium titanate and polyvinylidene fluoride, where a deformation of piezoelectric material gives rise to electrical energy. The recently invented triboelectric generator harvests mechanical energy through a periodic contact motion based on the coupling of the triboelectric and electrostatic effects, and many approaches have been carried out to improve the electrical output performance of the triboelectric generator [8][9][10][11][12][13][14][15][16] .…”

Aerodinámica no-estacionaria en perfiles de aerogeneradores

“…Recientemente, el interés en el fenómeno de galope se ha incrementado debido a su uso potencial como una fuente de energía renovable y se han publicado trabajos acerca del uso de ciertos mecanismos para la extracción eficiente de energía eléctrica mediante convertidores de energía (piezoeléctricos, electromagnéticos, etc.) (Ng et al, 2005, St. Clair et al, 2010, Peng and Chen, 2012.…”
