Abstract

Solar radiation is strongly absorbed by soot aggregate. And the atmospheric radiative properties will be affected by the change of aggregate morphology. Based on fractal theory, the morphological properties of soot aggregates are studied using the cluster-cluster aggregation (CCA) model. The superposition T matrix method is employed to perform extensive computations of extinction, absorption and scattering properties of soot aggregates with varying state of compactness and size. The relationship between the morphology and radiative properties of aggregates is discussed. Firstly, the radiative properties of different size and different morphology of aggregates are analyzed with the change of the volume fraction. Then, the absorption, scattering and extinction cross-sections of a fixed morphology aggregate are analyzed with changing particle size. Finally, an essential data for detecting soot aerosol concentration can be provided by the value of absorption cross-section of our results.

烟尘凝聚体形态对浓度检测辐射特性的影响

太阳辐射被烟灰聚集体强烈吸收。聚集体形态的变化会影响其大气辐射性能。基于分形理论，采用聚簇-聚簇(CCA)模型研究了煤烟聚集体的形态特性。采用叠加T矩阵法对不同密实度和尺寸的烟尘聚集体的消光、吸收和散射特性进行了广泛的计算。讨论了聚集体的形态与辐射性能之间的关系。首先，分析了不同粒径、不同形态的聚集体的辐射特性随体积分数的变化。然后，分析了固定形态聚集体的吸收、散射和消光截面随粒径变化的变化。最后，所得结果的吸收截面值为检测烟尘气溶胶浓度提供了必要的数据。
