Notes:
Residence-time studies are reported for water trickling down through a 4-in. column packed with spheres. The transient response of the column to pulse- and step-function inputs in tracer concentration applied to the water stream was determined for both porous and nonporous packing. Significant radial variations in the distribution of residence times and the volumetric rate of flow were observed. The contribution to the response curves of diffusion into the porous packing and flow in the interparticle voids can be separated. The diffusion rates may then be characterized in terms of an effective pore diffusivity for the packing.
