Tóm tắt

This paper presents a novel dual serial vortex-induced vibration energy harvesting system for enhanced energy harvesting. It consists of two identical cantilever-based piezoelectric vortex-induced vibration energy harvesters, which are successively installed in one plane (which is paralleled with the wind flow direction) of the wind tunnel. The Lattice Boltzmann method is employed to predict the strength of vortex-induced vibrations and the pressure distribution around the circular cylinders of the harvesters. The numerical results qualitatively explain the influence of the space distance on the energy harvesting performance of the presented system. Experimental results verify the numerical analysis and demonstrate a higher energy harvesting efficiency of the presented system over its traditional single harvester. In detail, experimental results indicate that the effective wind speed range and the output power area of a coupled harvester in the presented system can be as many as 2.67 times and 6.79 times of that of the traditional single harvester, respectively.
