ON THE THERMAL CONDUCTIVITY OF A BLOWN GRANULAR BED
V. I. Kovenskii and Yu. S. Teplitskii UDC 532.5 Dependences for calculation of the effective thermal-conductivity coefficients of a granular bed and its constituent phases have been obtained by analogy with the processes of convective heat and mass transfer. The dependences involve simple and quite reliable formulas for calculation of the conductive thermal conductivity of an unblown bed and the radiative thermal conductivity of the skeleton of solid particles.
