双色法同时测定碳氢火焰温度和碳粒体积分数

Simultaneous reconstruction of hydro-carbonic flame temperature and soot volume fraction using two-color pyrometry

推导了由碳氢火焰中某点的辐射能同时得到该点温度和碳粒体积分数的表达式 ,在双色法的基础上 ,引入光学CT技术来重建整个碳氢火焰的辐射能 ,并进而确定碳氢火焰各点的温度和碳粒体积分数 .对已有实验数据进行模拟运算表明 。

An equation was deduced which could get the temperature and soot volume fraction simultaneously from the radiative energy of a point in hydro-carbonic flame. Based on two-color method, optical CT was used to reconstruct the radiative energy of the whole hydro-carbonic flame. The temperature and soot volume fraction was got. The previous experiment data was used for good simulation.
