摘要

基于辐射等效介质理论，建立了纳米多孔材料的光学和辐射特性参数理论模型，计算了纳米多孔材料的有效热辐射特性参数。基于非灰体各向异性的Rosseland近似，建立了纳米多孔材料辐射换热模型，计算了纳米多孔材料的辐射热导率，分析了含不同遮光剂纳米多孔材料的辐射热导率与颗粒体积份额、颗粒平均直径的关系，揭示了纳米多孔材料内部辐射换热与多尺度结构特征和材料属性间的本构关系，为纳米多孔材料结构参数优化设计提供了依据。

Abstract

Based on equivalent medium theory，a model for nanoporous materials optical and radiative properties was proposed.Effective thermal radiation characteristic parameters were computed.Based on the non-gray anisotropically scattering Rosseland approximation，the model that can be used to quantify the level of radiation heat transfer traveling through nanoporous materials was developed.The radiation thermal conductivity of the nanoporous materials was computed.The relationships between the radiation thermal conductivity and the population volume fraction and the population diameter of nanoporous materials with different opacifiers were analyzed.The constitutive relation between the internal radiation heat transfer and multi-scale structural features and material properties of the nanoporous materials was revealed.In the future，this model should guide the design of new nanoporous materials with optimized radiative properties.
