Pure Radiative heat exchange of a thin Fin

An equation to evaluate pure radiative heat exchange of thin fins is proposed and analytically solved; equation solution may be conveniently employed to determine shadowed conditions thermal field of antennas, solar panels, tethered devices, remote controlled arms and heat dissipation systems on space facilities. Solution is compared to the results of a numerical simulation which has been carried out by means of a finite volumes code (Fluent); a good agreement has been found between simulated and analytical results. It is meant to verify the proposed method by an experimental setup which will be designed to be hosted on future space research mission.
