摘　　要：微动力系统是动力机械具有里程碑意义的发展。由于能量密度的极大优势,应用燃烧释放碳氢燃料的化学能转化为电能或者机械能的微动力系统有巨大的发展潜力和广阔的应用前景。微燃烧室是该类微系统的核心,本实验建立了1mm以下尺寸的平行板微燃烧室内的流动、传热和燃烧模型,在实验验证的基础上,用CFD软件进行了数值模拟,获得了亚毫米平行板通道高度、混合气流量和比率等参数对内部燃烧情况及壁面温度的影响规律。Micro-power system is the milestone of the development of power devices.Because of its great advantage in energy density,micro-power system has great development potential and broad prospects for application,which releases the chemical energy of hydrocarbon fuel form burning,and transfer it into electric energy or mechanical energy.A micro-combustor is one of the most important components of a micro-power system.Based on the establishment of mathematical model of the parallel plated micro-combustor under one millimeter and experimental test,combustion in the combustor and wall temperature distribution under different parameters such as height,flow rate and mixing rate were simulated using fluent software.Furthermore,the effects of these parameters on the combustion in the combustor and on the wall temperature distribution were analyzed.
