微尺度爆震燃烧研究进展

Progress in the microscale detonation research

微尺度爆震燃烧(Microscale Detonation)是基于微燃烧(Microscale Combustion)和微动力机电系统(Power MEMS)提出来的新研究方向。目的是为了把爆震燃烧这一高效的燃烧方式应用于微动力领域,以解决人们对小型、高性能动力的需求。几十年来,人们虽然在爆震燃烧的研究中涉及了一些与微爆震相关的内容,但是对其机理的了解仍然十分不足。本文从微爆震基本概念出发,对其现象、成因、影响因素及需要解决的问题等方面进行综述,总结了目前国内外重要的研究成果,为今后进一步的探索提供参考。

Microscale detonation is a new research subject based on the concepts of microscale combustion and power micro electro mechanical systems, which aims to meet the increasing de- mand for small but high performance power system by utilizing detonation combustion with high thermal efficiency. Although microscale detonation research has partially been involved in the conventional investigations of detonation for decades, its fundamental mechanisms are still poorly understood. In this paper, an overall review on the phenomenon, origins, influence factors and challenges of microscale detonation as well as its basic concepts is provided. Significant results to date are summarized, which may contribute to the further exploration of this suh]ect.
