Evaporative heat and mass transfer for the diffusion driven desalination process

An innovative Diffusion Driven Desalination process was recently described where evaporation of seawater is driven by diffusion within a packed bed. This work describes the evaporative heat and mass transfer analysis for the packed bed. Temperature and humidity data have been collected over a range of flow conditions at the inlet and outlet of the packed bed. The analysis agrees very well with the experimental data collected during this investigation and that which has been reported in the literature.
