摘要

为实现海流驱动压电俘能器振动发电,给海洋中的各类低功耗监测传感器供能,基于涡激振动原理,设计一种采用改良阻流体的压电俘能系统,以提高发电性能。分别对阻流体和压电悬臂梁结构进行优化设计,基于COMSOL Multiphysics软件,仿真分析6种不同阻流体结构诱导产生的涡街特性,并选用最优阻流体结构开展流-固-电全耦合仿真。研究海流流速、阻流体尺寸对阻流体和压电悬臂梁上的升阻力系数以及压电悬臂梁输出电压的影响。仿真结果表明,优化设计的压电俘能结构可提高俘能系统的输出电能,在海流流速0.5 m/s、阻流体尺寸0.02 m条件下压电悬臂梁开路电压为0.8 V。

Abstract

To convert the kinetic energy from ocean currents into electrical energy, a piezoelectric energy harvesting system based on vortex-induced vibration （VIV） was designed. The structures of the bluff body and piezoelectric cantilever beam were optimized to increase the input fluid kinetic energy and output electrical energy. The vortex streets induced by six different bluff bodies were simulated and compared by using COMSOL software. Finally, the optimal bluff body was used to carry out fluid-solid-electric full coupling simulation. The influence of different Reynolds numbers on the lift and drag coefficients of the bluff body and the piezoelectric cantilever beam were analyzed and compared, as well as the open-circuit voltage （OCV） of the piezoelectric cantilever beam. The simulation results showed that the optimized piezoelectric energy harvesting structure can improve the output electrical energy of the energy harvesting system, and the OCV of the piezoelectric cantilever beam is 0.8 V under the condition of current velocity of 0.5 m/s and bluff body size of 0.02 m.
