摘要
关于微型燃烧设备的研究,可代替电池的利用。针对探索微尺度燃烧的特性和影响微尺度燃烧的问题,为了优化燃烧的稳定性,采用管径为1mm,2mm,3mm的三种微陶瓷管燃烧器为研究对象,并在燃烧器外加高压电场,利用fluent6.3仿真软件对微尺度燃烧器内甲烷和空气的流动和燃烧进行数值仿真,找出了微尺度条件下燃料燃烧的流场、温度场以及转化率与外加电压、燃空比以及陶瓷管管径的关系。经试验证明,为微燃烧器优化设计提供了有效的参考依据。
In order to discover the micro scale combustion characteristic and the influence factors of micro scale combustion, three ceramic tube burners with diameters of lmm, 2mm and 3mm were selected as research object. High voltage electric field was added out of the burners. Combustion of methane and air in micro - burner is emulated through software Fluent6. 3. The relationship among flow field, temperature field and transformation ratio and applied voltage, fuel air ratio and ceramic tube caliber was found out. And this is as the basis for optimizing design of micro combustor.
