Paper Abstract

Theoretical analysis of the interaction between concentrated solar radiation and an honey-comb matrix or a bed of particles cooled by a gas is proposed. The computation and the ex-perimental results show evidence of an overheating of the solid near the irradiated surface. To prevent the upper surface from this phenomenon and to reduce the radiative heat losses, we propose to use selective semi transparent porous absorbers. First results about coatings on silica are presented.
