本文从米氏电磁散射理论出发， 计算了含液滴介质的辐射特性。考察了各向同性散射能量传递份额的再分配， 导出了吸收、发射、各向同性散射介质的辐射传递系数。计算了空间辐射散热器液滴层瞬态辐射换热， 经与文献 ［４， ５］ 的比较表明， 本文所导出的辐射传递系数计算方法正确， 精度高。用计算机辅助实验， 分析液滴发生器产生粒子的大小、粒径分布对瞬态辐射换热的影响， 可减少空间辐射散热器设计过程中的实验次数。
In this paper, based on the theory of Mie scattering, the radiation characteristics of liquid with droplet are calculated. The redistribution of the energy transfer share of isotropic scattering is investigated, and the radiation transfer coefficients of the absorbing, emitting and isotropic scattering media are derived. The transient radiation heat transfer of the radiation layer of the radiant radiator is calculated. Comparing with [4] and [5], the radiative transfer coefficient derived in this paper is correct and accurate. Computer-assisted experiments were used to analyze the influence of particle size and particle size distribution of the droplet generator on transient radiative heat transfer, which can reduce the number of experiments in the design process of radiant radiator.
