为了改善LII作为提取烟尘性质的定量工具，描述颗粒与周围气体之间的传热和传质的模型必须针对表征良好的实验进行测试。在这项工作中，我们已经做了详细的调查，其中实验结果进行了比较，在两个不同的配置，向后LII和90 o-LII的模拟。虽然结果显示出定性良好的一致性，但人们意识到，需要对LII信号行为进行改进的物理描述。
To improve LII as a quantitative tool for extraction of soot properties, the models describing the heat and mass transfer between the particles and the surrounding gas must be tested against well-characterized experiments. In this work we have made a detailed investigation in which experimental results have been compared with simulated ones in two different configurations; backward-LII and 90o-LII. Although the results show a qualitatively good agreement, it is realized that an improved physical description is needed for the LII signal behavior.
