Experimental Investigations of Heat Transport Dynamics in a 1d Porous Medium Column

The present study involves the experimental investigation of heat transport due to the forced convective flow through a thermally isolated porous medium column. The experiments regard the observation of thermal breakthrough curves obtained through a hot flow injection in correspondence of two thermocouples positioned along a thermally isolated column of porous medium. The experiment has been carried out for three flow rates in order to investigate the critical issues regarding heat transport phenomena such as the relationship between the thermal dispersion with the flow velocity and the validity of the local thermal equilibrium assumption between the fluid and solid phase.
