Radiative Heat Transfer of Spherical Particles Mediated by Fluctuation Electromagnetic Field
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).
