Many industrial applications of random packed beds of solid particles involve axial high temperature heat transfer. The mechanisms of conduction and radiation have been evaluated independently of convective effects for such systems using a modified geometric model which allows for flux line bending in the solid phase. This model has been used to analyse experimental measurements for heat transfer in a stagnant bed of inert alumina-silicate balls over the temperature range 20-750°C. Comparisons with other theoretical models and experimental data are also made. © 1971.
