| 摘 要： | 从偶极辐射理论出发,结合普朗克黑体辐射分布,推导出近场区热辐射分布。采用MC法模拟了两个纳米球形 村子的辐射换热,考察相天参数对近场辐射换热的影响。表明其辐射热流可比黑体辐射高8个数量级。其热流随间距的增 大急剧减小。小研究对于纳米粒子群的传热研究有积极意义。

| Abstract: | Based on the principle of electric dipole radiation and the Planck's spectral distribution of emissive power, the enhancement of thermal radiation between two micro spheres was studied in this paper by the Monte Carlo method. Some parameter's influence on the radiative heat transfer was investigated. The results show that heat transfer can be enhanced by eight orders of magnitude for the near-filed effect. And the radiative heat transfer is decreasing sharply with the increasing of the distance. This study is important to the heat transfer of group nano-particles. |
