摘　　要：基于燃料燃烧的微型能源动力装置具有高能量密度特性,可提供瓦到百瓦级的能量输出,因此在过去的20年间受到广泛关注。国内外学者研制了微型的燃气轮机、内燃机、推进装置、燃烧器、热电转换装置及热光电转换系统等不同类型的能源动力装置。然而,由于微尺度条件下燃烧环境和常规尺度存在差异,材料、密封及润滑等方面的技术瓶颈,目前大部分微型能源动力装置的性能未能到达预期的目标。由于微尺度燃烧基础理论有别于传统的常规尺度燃烧理论,随着其重要性的凸显,国内外学者对其进行了广泛深入的研究,更加清晰地揭示了微尺度火焰及燃烧的基本特性。本文首先介绍了国内外微型能源动力装置及系统的研究进展,然后对微尺度条件下预混及非预混火焰的研究现状进行了总结,在本文的最后部分提出了微燃烧相关亟待解决的科学及工程问题。Combustion based micro energy and power systems which can provide power at hundred watts have attracted attentions in the last twenty years.Micro gas turbines,micro engines,micro-thruster,micro combustors,micro thermoelectric power generation system and micro-thermophotovoltaic(TPV)power generators have been developed.However,the combustion characteristics of flame in micro scale are different from that in normal scale.Also,the materials,sealing and lubricating technologies facing severe challenges in micro scale.So far,most of the combustion in micro energy and power systems did not achieve desired performance.The fundamental studies on micro combustion have been conducted for the development of micro energy and power systems.The understanding on micro flames is more clearly with continuous efforts.In this paper,the combustion based micro energy and power systems were introduced,and the fundamental studies on micro flames were summarized.
