Summary

COMBINED RADIATIVE, CONDUCTIVE, AND FORCED CONVECTIVE HEAT TRANSFER THROUGH A PACKED BED COMPOSED OF 2 SPECTRALLY DISSIMILAR SLABS OF PARTICLES IS ANALYZED ON THE BASIS OF THE TWO-FLUX MODEL. TAKING INTO ACCOUNT THE VARIATION OF ABSORPTION AND SCATTERING OF THE LAYERS IN THE VISIBLE AND INFRARED SPECTRAL RANGES, THE SELECTIVITY OF SUCH A SYSTEM IS PROVED THEORETICALLY. EXPERIMENTS ARE RUN USING A BED COMPOSED OF GLASS AND SILICON CARBIDE PARTICLES AS A SOLAR ABSORBER FOR GAS HEATING. GOOD AGREEMENT IS SHOWN IN THE COMPARISON OF PREDICTIONS WITH EXPERIMENTAL DATA.
