Energy and exergy analyses in convective drying process of multi-layered porous packed bed

An Overview on Application of Exergy and Energy for Determination of Solar Drying Efficiency

“…[58] This mathematical approach can be used to study thin or packed bed drying with a media supposed as porous [56,62]. …”

Theoretical and experimental study of heat and mass transfer mechanism during convective drying of multi-layered porous packed bed

“…In the case of two-layered packed beds (F-C bed and C-F bed), the moisture content profiles become discontinuous at the interface between the two layers [23], namely, the moisture content in the upper layer is higher than that for the lower layer in F-C bed, while the moisture content in the upper layer is lower than that for the C-F bed. This is because the equilibrium water saturation under the same capillary pressure differs according to the particle sizes with the smallest particle size corresponding to higher water saturation.…”

Exergy transfer characteristics of gas-solid heat transfer through sinter bed layer in vertical tank

“…In recent years, the exergy analysis of convective heat transfer process has been discussed and demonstrated. Prommas et al [7,8] studied the energy and exergy analyses in convective drying process of multi-layered porous media and in the drying process of non-hygroscopic porous packed bed, and presented the investigations on the effects of porous structural parameters and thermodynamics conditions on energy and exergy profiles. Bindra et al [9] investigated the thermal analysis and exergy evaluation of thermal energy storage in a packed bed during cyclic storage and recovery.…”
