摘要
建立了基于Kubelka-Munk理论的红外隐身涂层发射率仿真计算模型。以Al粉颗粒作为颜料粒子,采用Maxwell-Garnett有效介质理论计算分析了涂层的等效折射率与波长的关系。从电磁波与颜料相互作用的机理出发,采用几何光学理论计算得到了涂层的吸收系数和散射系数。定量分析了铝粉颗粒粒径以及体积分数对涂层发射率的影响。结果表明,该模型对红外隐身涂层的制备具有一定的指导意义。
A simulating model of emissivity of infrared stealth coating based on Kubelka-Munk theory is put forward. Taking aluminum particles as pigments, using Maxwell-Garnett effective medium theory, the relationship between equivalent refractive index of coating and wavelength is calculated and analyzed. Based on the mutual interaction of the electromagnetic wave and pigments, adopting geometrical optical theory, scattering and absorption coefficients of the coating are calculated. Effects of aluminum particlesr parameters, such as size and volume, to the emissivity of coating are analyzed quantitatively. The result shows that the proposed model could be used to guide the preparation of infrared stealth coating.
