摘　　要：最大化提高微燃烧室的燃烧效率对于微热光电系统是非常关键的。建立了微燃烧室内的流动、传热和燃烧模型并进行了数值模拟。利用试验结果验证了模型的可靠性。在此基础上,模拟了带有环形翅片燃烧室的情况,表明环形翅片能增强微燃烧室内混合气体的湍流扰动,改善燃烧状况,有效地提高燃烧效率。Increasing the combustion efficiency of the micro combustor to the greatest extent is very important to the micro thermophotovoltaic systems. Flow, heat transfer and combustion models were built for the micro combustor, and numerical simulation work were conducted. The reliability of the models was validated by experimental results. Based on the research, simulates the combustor with a ring fin indicate that the ring fin can enhance the turbulence of the mixed gas in the combustor, improve combustion status, increase the combustion efficiency availably.
