摘　　要：介绍了一种新颖的微动力机电系统, 即微热光电系统。该系统可以取代电池作为各种微型机械的动力,广泛应用于民用与军工部门。微燃烧器是微热光电系统的一个重要元件, 其外表面必须产生一个高而均匀的温度分布,以尽可能高地输出辐射能。结合三维数值模拟与实验对微燃烧室进行了研究。研究结果表明,带有台阶的微火焰管燃烧室非常适合于微热光电系统的应用。A novel power MEMS device, micro thermophotovoltaic (micro-TPV) system was introduced in this work. It can replace traditional batteries as the power source of all kinds of micro devices for civilian and military application. As one of the most important components of micro-TPV system, micro combustor should be able to produce a high and uniform temperature distribution along the outer surface to ensure a high radiation power density. To testify the feasibility of micro combustion, a lot of 3-D numerical simulation and experimental tests were carried out. The results indicate a micro flame tube combustor with a backward facing step is one of the most effective combustors for micro-TPV application.
