Nanosphere Near-Field Radiative Heat-Exchange Analysis

摘要

A theoreticalmethod for sphere-to-sphere radiative heat exchange is implemented for silica, lithiumfluoride, andnarsenic selenide nanospheres of equal and unequal radii. The method is extended to approximate a sphere-to-planengeometric configuration via an asymptoticmethod.The asymptoticmethod calls for an iterative process bywhich thenradiative exchange is continuously calculated up to convergence while increasing one microsphere radius. Thesenresults are compared with previously published theoretical approximations and experimental data.
