TRANSIENT ANALYSIS OF INCOMPRESSIBLE-FLOW THROUGH A PACKED-BED

The present investigation aims at numerically simulating the temporal energy transport for incompressible flows through a packed bed. The go verning equations are formulated according to the volume averaging met hod. The generalized momentum equation which accounts for the inertial and viscous forces was used to carry out this research, whereas the t wo-energy equation model was used for simulating the energy transport. The implications of the non-Darcian terms and the thermal dispersion effects on the transient energy transport were explored. Error maps we re introduced for a wide range of flow conditions and bed configuratio ns. In addition, the investigation also tackles the applicability of t he local thermal equilibrium condition and the one-dimensional approac h for studying the thermal response in packed bed.
