In this paper heat transfer characteristics in air-solid packed bed with spherical steel particles are studied experimentally. The effect of particle sizes (${phi}1.5,;{phi}2.5,;{phi}3.96,;{phi}4.75,;{phi}5.95,;{phi}7.15$), bed sizes (${phi}50,;{phi}60,;{phi}70,;{phi}80$) and mass flow rate are investigated. Also heat transfer effect of the bed with particles and without particles is compared in terms of heat transfer coefficient. As a result of this experiments, the following relation is obtained in the range of the Reynolds numbers 40 between 1500. $Nu= 0.8755;Re^{0.6367}$ (40<Re<1500)
