聚甲氧基二甲醚高温高压下喷雾燃烧特性光学诊断研究
Optical Study on spray and combustion characteristics of polymethoxy dimethyl ethers under high-temperature and highpressure conditions
本文采用多种光学诊断方法，探究了聚甲氧基二甲醚PODE3 和PODE3-5 两种电力合成燃料在高温高压定容燃烧弹内的喷雾及燃烧特性. 此外，还应用正十二烷 (NC12)和混合燃料P50(50%PODE3、50%NC12，vol)作为参考燃料在相同的试验工况下也进行了测试. 试验过程中，采用高速纹影法获得了喷雾轮廓的演化过程和着火延迟期(ID)，应用OH*化学荧光法测定了火焰浮起长度(LOL). 此外，利用平面激光诱导荧光技术获得了甲醛和OH*的瞬…查看全部>>
The ignition and combustion characteristics of two electric synthetic fuels, polymethoxydimethyl ether PODE3 and PODE3-5, were investigated in a high-temperature high-pressure combustion chamber by means of multiple optical diagnostics. In addition, ndodecane (NC12) and a blend fuel P50 (50% PODE3, 50% NC12, vol) were tested under the same operating conditions as references. During the test, the ignition delay (ID) and spray evolution were quantified using a…查看全部>>
