摘要
随着微纳器件应用领域的日益拓展,微能源技术受到国内外研究人员的高度关注和重视,其中利用涡激振动进行流体能量收集是主要的研究热点。本文首先介绍了基于涡激振动的流体能量收集原理,归纳了涡激振动式微流体俘能器的典型结构、原理、特性和应用情况。其次,总结了国内外基于尾涡致动和钝体致振这两种主要涡激振动流体俘能技术的发展概况与研究进展,并简述了涡激振动压电式俘能器流固耦合数学模型的研究现状。最后,指出涡激振动能量收集尚缺乏统一的数学模型以及现有的俘能器存在结构可靠性低、稳定性较差等问题。在此基础上,分析了利用涡激振动实现流体能量收集接下来的发展趋势,以期推动涡激振动式微流体俘能器的进一步发展与应用。
With gradually expansion of the application field for micro-nano devices,micro energy technology have been paying more and more concerns and attentions by domestic and oversea researchers,among which micro fluid energy harvester based on the vortex-induced vibration（VIFEH）has become a hotspot.First,the operational principle of the VIFEH was introduced and the typical structure,theory,features and application situation of VIFEH were generalized.Then,the relative technology development and research progress of the fluid energy harvester with wake-induced vibration and that with vibrational bluff body were summarized and the research status of fluid solid coupling mathematical model for VIFEH was briefly described.The analysis results show that VIFEH still lack the uniform mathematical model and there are low reliability and comparably low stability in the existing VIFEH structure.Moreover,further development trend of VIFEH was pointed out.It is expected to promote the research and applications of VIFEH through this work.
