Abstract

Alumina particles occur multiphase in aircraft plume. The superposition T-matrix method was applied to study how the monomer models of multiphase alumina affects the optical characteristics of alumina cluster. The concentric monomers (CM), uniform direction monomer (UDM) and random direction monomer (RDM). In addition, to simplify the computation, we applied Maxwell–Garnett equivalent approach to simulate equivalent homogenous monomer (EHM). According to the results, the optical characteristics of alumina clusters with CM, UDM and RDM are almost the same. The relative discrepancies of using EHM and using other three heterogeneous monomer models can not be ignored. Our research provides a suggestion for model simplification and selection. For the significant roles of alumina particles in plume radiation, our research is useful for application of detecting system.
