Abstract

Solar Vaporization using heat localization under solar irradiation has the potential to serve as an inexpensive and viable component of seawater desalination processes, industrial wastewater treatment, hydroponic greenhouse humidifiers, and steam generation systems. In this paper we tested different porosities of carbon foam (CF) and combinations of CF as interface media at 1.2 sun solar concentration, in search of a suitable candidate for use with distillation process. We developed an experimental condition to analyze how the heat localization is achieved in each case and investigated vapor temperatures, surface temperatures with single CF as interface. The rate of evaporation, temperature distribution in each combination is studied and suitable combination is selected to use in further testing of desalination model.
