Numerical investigation of coupled heat and mass transfer inside the adsorbent bed of an adsorption cooling unit

Multi-physical continuum models of thermochemical heat storage and transformation in porous media and powder beds—A review

“…Solmus ß et al [94] investigated the coupled heat and mass transfer mechanisms inside the adsorbent bed of a solid sorption cooling unit using the water/silica gel working pair aiming to design and optimise a new and more efficient adsorbent bed. The developed transient one-dimensional local thermal non-equilibrium model accounted for both internal and external mass transfer resistances.…”

“…The presented one-dimensional model incorporates intraparticle mass transport and heat transfer resistance around the particle. It was validated using literature data [94]. Neglecting losses to the environment, the model was used to predict the COP and SHP of the cylindrical bed configuration.…”

Investigation of Heat and Mass Transfer in Activated Carbon Granules/R-134a Adsorbent Pair for Compact Adsorption Chiller

“…They found that, the pressure distribution inside the adsorption bed was nearly uniform varying with time only, and the used adsorption pair thermal conductivity was constant in both space and time. Solmus et al [10] investigated numerically the coupled heat and mass transfer inside the adsorbent bed of a silica gel/water adsorption cooling unit, using a transient one-dimensional local thermal non-equilibrium model, which based on accounting both internal and external mass transfer resistances. They developed two different energy equations for the single phase adsorbate, and the solid phase adsorbent with the adsorbed adsorbate.…”

Modelling and Optimization of an Adsorption Cooling System for Automotive Applications

“…Solmus et al [64] developed a one-dimensional local thermal non-equilibrium model in order to study the heat and mass transfer mechanisms inside a cylindrical sorption bed. The model takes into account both internal and external mass transfer resistances.…”
