Experimental investigations are conducted on the pressure loss and heat transfer characteristics for packed beds of spherical particles. The spherical particles used in this experiment are glass and polystyrene beads, and the working fluid is air. The experiments on heat transfer characteristics are conducted by the unsteady method, and volumetric heat transfer coefficients are given by the method of fitting between transient temperature profiles of the solid and the gas phase calculated from the analysis and those obtained by the experiment. As a result of arranging these data by using a characteristic length which is defined by the pressure loss, it has been revealed that the experimental data are well arranged. Moreover, as a result of adding the data of the nonparticulate porous media such as a foamed metal and rearranging by the characteristic length, the heat transfer correlation which is able to comparatively well arranged has been obtained.
