| 摘 要： | 在设计和加工模块式微热光电系统关键部件的基础上,进行了系统的整体性能试验,包括流量、喷嘴形状和燃料对其性能的影响。试验结果表明：气体流量增加,燃烧室壁面温度升高,光电池的输出电量升高;相比圆形喷嘴,使用矩形喷嘴能改善预混合气在燃烧室内的分布,提高燃烧驻留时间,使燃烧更充分,增大光电池的电能输出;相同体积流量下,高热值的甲烷燃料比氢气燃料更能提高微热光电系统的性能。试验条件下较好的性能输出数据如下：当采用矩形喷嘴和甲烷燃料时,最大输出功率为0.319W,相应的能量密度达到166146W/m3;两种燃料最大整体效率都是在流量600mL.min-1时,且采用氢气燃料整体效率比甲烷的高,其最大效率为0.249%。

| Abstract: | Whole performance of the modular micro thermophotovoltaic system(MTPV) was tested,including influence of flow rate,nozzle shape and fuels,based on the design and fabrication of the key components of the system.The results showed: wall temperature and photocell output were increasing with the increase of flow rate.Square nozzle could improve the pro-mixed gas distribution and residence time compared with circle nozzle,so combustion was more sufficient,which resulted in the increase of photocell output.Due to... |
