Abstract
Abstract. The present study is aimed at extending this thematic issue through heat
transport experiments and their interpretation at laboratory scale. An
experimental study to evaluate the dynamics of forced convection heat
transfer in a thermally isolated column filled with porous medium has been
carried out. The behavior of two porous media with different grain sizes and
specific surfaces has been observed. The experimental data have been compared
with an analytical solution for one-dimensional heat transport for local
nonthermal equilibrium condition. The interpretation of the experimental data
shows that the heterogeneity of the porous medium affects heat transport
dynamics, causing a channeling effect which has consequences on thermal
dispersion phenomena and heat transfer between fluid and solid phases,
limiting the capacity to store or dissipate heat in the porous medium.
