利用多通道高温计测量燃料高速燃烧动态温度的方法,在爆炸激波管中模拟异辛烷,正庚烷、正辛烷、正庚烷+异辛烷混合物等烷烃高速燃烧。并用该方法考察了氧气对异辛烷高速燃烧温度的影响,及上述烷烃的辛烷值与高速燃烧温度的关系。结果表明,对于富含异辛烷的混合物,增加氧含量可以使高速燃烧温度增加;随着烷烃辛烷值的增加,高速燃烧温度下降,与利用传感器测量结果相吻合。本文所述的方法可以用于各种气-液相混合物高速燃烧温度的测量。
The multi-channel pyrometer was used to measure the dynamic combustion temperature of high-speed fuel combustion. The explosive shock tube was used to simulate the high-speed combustion of paraffins such as iso-octane, n-heptane, n-octane, n-heptane + isooctane mixture. The effect of oxygen on the high-speed combustion of iso-octane and the relationship between the octane number of the alkane and the high-temperature combustion temperature were investigated. The results show that for the isooctane enriched mixture, increasing the oxygen content can increase the high temperature combustion temperature. With the increase of the octane number of alkane, the high temperature combustion temperature decreases, which agrees with the measurement result of the sensor. The methods described herein can be used to measure the high temperature combustion temperatures of various gas-liquid mixtures.
