HEAT EXCHANGE BETWEEN AN INFILTRATED GRANULAR BED AND A SURFACEYu. S. Teplitskii UDC 532.546 Comparative analysis of the existing relations for calculation of convective heat exchange between an infiltrated granular bed and surfaces of different geometry has been carried out. It is shown that different characteristic scales of the process of heat and mass transfer correspond to laminar and turbulent modes of filtrational flow. The occurrence of an analogy with heat transfer of a single-phase medium in a laminar mode has been found. A correlation for calculation of heat exchange between a vertical cylinder and an infiltrated granular bed has been obtained. A. V.
