A review on adsorption heat pump: Problems and solutions
Adsorption heat pumps have considerably sparked attentions in recent years. The present paper covers the working principle of adsorption heat pumps, recent studies on advanced cycles, developments in adsorbent-adsorbate ...
A comment on change of Nusselt number sign in a channel flow filled by a fluid-saturated porous medium with constant heat flux boundary conditions
The aim of this Letter is to show that, the Nusselt number sign might be changed without changing of heat transfer direction at the wall of channels, even for flows without viscous dissipation. The sign of the Nusselt ...
Thermal dispersion in porous media - A review on the experimental studies for packed beds
(American Society of Mechanical Engineers, 2013)
Thermal dispersion is an important topic in the convective heat transfer in porous media. In order to determine the heat transfer in a packed bed, the effective thermal conductivity including both stagnant and dispersion ...
