“…In the cases that are analyzed in this work the reference angle of attack, α = 0 • , is that where the flow is parallel to the rectilinear side of the circular segment (see Figure 1). This angle of attack is of interest for simulating the aerodynamic response of footbridge decks, the gliding performance of certain animal species or the feasibility of circular segments with different corner angles, attached to the end of a piezoelectric cantilever beam, to act as relatively low-drag energy harvesters under flow-induced motions such as flutter, galloping, vortex-induced vibration or buffeting (Rostami & Armandei, 2017).…”

“…Furthermore, in recent years, in the field of vibration-based energy harvesting, that is the process of transforming ambient and aeroelastic vibrations to a usable form of energy with the objective of developing self-powered electronic devices (Abdelkefi, 2016), semicircular cylinders attached to the end of a piezoelectric beam have been studied as galloping-based aeroelastic energy harvesters. Comprehensive reviews on aeroelastic-based energy harvesting can be found in Abdelkefi (2016) or Rostami and Armandei (2017), while some specific references that focus on the galloping excitation of a semicircular geometry for energy harvesting are Abdelkefi, Hajj, and Nayfeh (2013); Abdelkefi, Yan, and Hajj (2014); Barrero-Gil, Alonso, and Sanz-Andres (2010) or Sirohi and Mahadik (2012), amongst several others. Typical Reynolds numbers of these galloping-based energy harvesters are between 10 4 and 10 5 .…”

This paper presents the results of numerical and experimental investigations on the force coefficients and Strouhal numbers of circular segments considering different corner angles or chord to sagitta ratios. The research is motivated because these geometries are becoming increasingly popular in several engineering disciplines. The so-called D-section (semi-circular cylinder with a corner angle of 90 •) has been experimentally studied in the past, since it is a galloping prone geometry. However, there is a lack of research for cases with different corner angles, and the numerical investigations related to this topic are particularly scarce. In this work, a 2D Unsteady Reynolds Averaged Navier-Stokes approach has been adopted aiming to study the circular segments at the sub-critical regime, considering corner angles from 40 • to 90 • , and the flow parallel to the rectilinear side. These sections were found to be particularly challenging since they present massive flow separation on the rectilinear side, alongside the inherent difficulties related to modeling the flow along curved surfaces at high Reynolds numbers. The impact of introducing low-Reynolds-number and curvature corrections in the k − ω SST turbulence model and the performance of the Transition SST model have been extensively studied.

“…Although significant attention was given to the piezoaeroelastic energy harvesting, the lack of study on a more practical aerodynamic loading is concerned [8]. As reviewed in [31], Mainly the studies focused on resonance and instability phenomenon, i.e., Vortex-Induced Vibration, flutter. To the authors ′ knowledge, in addition to the works done by De marqui et al [13,14], only a few articles [34][35][36][37][38][39] presented the evaluation of the lifting structure under a more practical aerodynamic loading condition, i.e., cruise and gust loads.…”

In this paper, a novel iterative finite element method (FEM) for energy harvesting purpose is presented. The new iterative FEM is implemented to solve the dynamic problems of piezoelectric-based energy harvester in the frequency and time domains. The validation against other methods from the literature shows the robustness and capabilities of the iterative FEM. Implementation to a transport aircraft wingbox with 14.5 m half span and an embedded piezoelectric layer is shown in some details. The energy harvesting potential of the wingbox due to the cruise and the 1-cosine gust loads is investigated. In addition, for the first time, stress and failure analyses of the structure with an active energy harvesting layer are performed. The results pointed out that the wingbox is still in a safe condition even when it is subjected to a 30 m/s gust amplitude while harvesting 51 kW power.

“…Vortex-induced vibration (VIV) or flow-induced vibration (FIV) [1] is receiving increasing attention as a new form of renewable energy source since the first prototype was invented by Bernitsas et al [2,3] in 2005. Various kinds of prototypes combining VIV with other technologies such as vibrators, and a linear/rotating generator, were designed in recent years.…”

Abstract:A novel vortex-induced piezoelectric energy converter (VIPEC) is presented in this paper to harvest ocean kinetic energy in the underwater environment. The converter consists of a circular cylinder, a pivoted plate attached to the tail of the cylinder, several piezoelectric patches and a storage circuit. Vortex-induced pressure difference acts on the plate and drives the plate to squeeze piezo patches to convert fluid dynamic energy into electric energy. The output voltage is derived from the piezoelectric constitutive equation with fluid forces. In order to evaluate the performance of the VIPEC, two-dimensional computational fluid dynamics (CFD) simulations based on the Reynolds averaged Navier-Stokes (RANS) equation and the shear stress transport (SST) k-ω turbulence model are conducted. The CFD method is firstly verified for different grid resolutions and time steps, and then validated using simulation and experimental data. The influences of the plate length and flow velocity on the wake structure, the driving force and the performance of the VIPEC are investigated. The results reveal that different parameters reach their peaks at different plate lengths, and the converter has a maximal output voltage of 2.3 mV in a specified condition and the maximal power density reaches 0.035 µW/m 3 with a resistance load of 10 MΩ. The influence of the simulated subcritical Reynolds number on the driving force is not noticeable. The simulation results also demonstrate the feasibility of this device.
