“…When configuring our simulation files (fvScheme and fvSolution), we adhere to the best practices recommended by both the OpenFOAM community and Wolf Dynamics [60], as shown in Table (3). This involves employing cell-limited Gauss linear schemes for gradient computations, utilizing Gauss linearUp-windV for divergence in Overset mesh scenarios, and adjusting relaxation factors to finely control convergence.…”

“…The morphing process of the flexible flapping foil is conducted by controlling the movement of the foil's membrane, which is added to the flapping motion (heaving and pitching). To show the flexibility of the flapping foil, a representation of the current foil configuration is shown in Figure (3). A NACA0012 foil in a uniform flow with a velocity U ∞ is forced to heave and pitch around a fixed axis with given kinematics (heave h(t) and pitch angle θ t (t)).…”

The influence of wing deformation in animal propulsion and motion is an intriguing phenomenon that has contributed to a growing interest in biomimetics in both academia and industry. The study focuses on developing a robust numerical tool for analyzing the motion of biological systems in fluid flows, crucial to understanding fluid-structure interaction (FSI) phenomena. The research introduces a new mesh deformation solver, dynamicOversetZoneFvMesh, designed to address limitations in OpenFOAM's conventional Overset method. This solver enables the application of both rigid body motion and deformation at specified patches within certain zones, allowing for more complex motion scenarios. Through meticulous verification, parallelization, validation, and mesh convergence studies, the modified Overset solver's reliability is confirmed. Two cases are examined: a rigid-body flapping foil and a flexible foil with leading-edge deformation. Results demonstrate the adapted solver's proficiency in managing complex fluid dynamics and accommodating simultaneous motion and deformation. Furthermore, the study reveals that leading-edge flexibility improves the power extraction efficiency of flapping foils, aligning with previous literature. Overall, the research lays the foundation for advancing FSI simulations and opens avenues for addressing previously challenging problems in the field.

“…Such an advancement would make technology viable even for smaller fish. For instance, Alqaleiby et al [7] determined that because of the low energy harvested by a piezoelectric element, attaching a piezoelectric energy harvester does not impact the swimming activities of a fish. Cha et al [8] explored the feasibility of harvesting energy from the motion of a robotic fishtail modelled to replicate the swimming pattern of a thresher shark utilizing bimorph piezoelectric beams, while Li et al [9] demonstrated, through experiments on robotic and live chinook salmon fish, the viability of sub-dermally embedded piezoelectric harvesters.…”

Monitoring of aquatic life is important for assessing long-term impacts on activities associated with fish stock and migration. One promising approach for long-term monitoring involves the development of self-powered telemetry devices capable of powering themselves by harnessing energy from the fish body undulations using implanted devices or from fluid motions generated by fish swimming using external devices. One of the latter devices is a broadband low frequency nonlinear bistable energy harvester. This cost-effective harvester has been inspired from the doubly curved leaf blades of a Venus-fly trap. This work examines the static behavior of such a bio-inspired bistable energy harvester by analyzing its force-displacement characteristics. The objective is to identify crucial design parameters to optimize the harvester's performance for potential application in self-powered fish telemetry tags. The unique characteristics of hysteresis loop and snap-through discontinuity of the harvester are investigated using finite element analysis. The finite element model is found to qualitatively replicate experimental observations. Additionally, geometrical and assembly parameters that affect the force-displacement behavior of the harvester are identified. A sensitivity analysis is performed to determine the effect of the aspect ratio, buckling displacement and thickness of the proposed harvester on the static force-displacement curve.

With the micro-miniaturization of offshore wireless sensors, signal lights, and other devices and the emergence of the problem of self-powering in the distant sea, how to harvest energy from low-speed currents has become a hot spot of research nowadays. To improve the energy output power and conversion efficiency of low-speed water flow, we propose a vertical cantilever beam circular cylinders fitted with a rigid splitter plate piezoelectric energy harvester (CSPPEH). In this paper, the influence of the length and the attack angle of the splitter plate on CSPPEH has been experimentally investigated. The vibration response mechanism involving the mutual transition between vortex-induced vibration and galloping was analyzed through particle image velocimetry flow field visualization. The experimental results indicate that the vibration and piezoelectric characteristics of the CSPPEH increase initially and then decrease with the length of the splitter plates (L/D = 0–2.4) at the attack angle of 0°, which can be explained by the theoretical model of the energy harvester. It is found that the optimal vibration and piezoelectric characteristics occur at a rigid splitter plate length of 1.40D with an attack angle of 90°. The maximum values for amplitude, vibration swing angle, voltage, power, and power density are 4.96D, 21.7°, 42.68 V, 910.81 μW, and 1.94 mW/cm3, respectively. Efficiency was up to 2.2% at 0.4D length and 90° attack angle of the splitter plate. Compared to the bare circular cylinder energy harvester, the output power and efficiency are significantly improved. The demonstration of continuous charging and discharging of capacitors and light emitting diode lights is performed to show the practicability of the designed CSPPEH. Overall, the present study enables the applications of CSPPEH for realizing self-powered wireless sensing and signal lights under low-water-speed environments.
