摘　　要：在碳化硅材料的亚毫米尺度微燃烧室内,针对甲烷和氢气两种不同燃料进行了燃料与氧气预混合燃烧的试验。利用热电偶测出燃烧室壁面温度并进行了分析。结果表明:在燃料和氧气的总体积流量相同时,燃用甲烷时燃烧室的壁面平均温度更高,但氢气的燃烧室壁面温度更加均匀,梯度更小;氢气比甲烷有更宽的可燃范围,试验时甲烷/氧气在总体积流量为700mL/min、混合比为化学当量比时燃烧不能进行,而氢气和氧气在相同条件下能够燃烧。Premixed combustion of fuels and oxygen in the sub-millimeter micro-combustor,which is made by silicon,was experimented for two different fuels of methane and hydrogen.Wall temperatures of the combustor were measured using thermocouple.The results show that the methane has higher average temperature than hydrogen in the same volume flow,but the wall temperature of hydrogen combustor is more uniform and have smaller gradient.Hydrogen has wider flammable range than methane.Methane can not be burnt when flow rate reached 700mL/min and mixing was stoichiometric in this experiment,while hydrogen can be burnt under the same condition.
