Hydrodynamic coupling of flexible flags in axial flows may profoundly influence their flapping dynamics, in particular driving their synchronization. This work investigates the effect of such coupling on the harvesting efficiency of coupled piezoelectric flags, that convert their periodic deformation into an electrical current. Considering two flags connected to a single output circuit, we investigate...
At present, energy harvesting from the widely existing fluid in the environment is a hot research field. Piezoelectric flags can be used to generate electric energy with the flow excitation for its positive piezoelectric effect. In this paper, the energy harvesting capacity of two piezoelectric flags in tandem arrangement in the uniform flow is analyzed through 2D numerical simulation. Identical vibration...
The dynamic performance and output power of two piezoelectric flags are greatly different from those of a single piezoelectric flag due to the coupling effect of each other. In this paper, the dynamic performance and energy harvesting ability of two piezoelectric flags in parallel arrangement in an axial flow are investigated using immersed boundary-lattice Boltzmann method coupled with Euler-Bernoulli...
