摘要:
本文计算了平衡真空背景(光子气体)中两个球形粒子系统的辐射换热强度和辐射电导。粒子的温度和背景辐射的温度是任意的。计算是基于波动电磁理论的偶极近似和加法近似。与A.Narayanaswamy和Gang Chen(Phys.Rev.,2008年)。
英文摘要:
We calculate intensity of radiative heat transfer and radiative conductance in a system of two spherical particles embedded in equilibrium vacuum background (photon gas). The temperatures of the particles and of the background radiation are arbitrary. The calculations are based on the dipole and additive approximations of the fluctuation electromagnetic theory. We obtained much higher radiative conductance between 25 mu silica particles (by 4 orders of magnitude) in comparison with recent results by A.Narayanaswamy and Gang Chen (Phys.Rev., 2008).
