Abstract
Evaporative solar desalination systems offer an economical method to produce pure water from brine solutions. In the present study, the effects of geometry (top surface inclination) and the surface wettability of the condensation plate on the performance of the basin-type solar desalination unit was investigated through the route of CFD (computational fluid dynamics) simulations. It was observed that inclination angle and surface patterning influence the overall rate of condensation. With the 26o top surface inclination, the rate of water production was 33.33% more than that of the 15o and 35o top surface inclinations. Surface wettability influences the production rate of pure water. A novel patterned condensation surface has been proposed, which can enhance the rate of condensation by 12.8% to produce more purified water. The patterned surface was obtained by placing alternate patches of hydrophilic and hydrophobic layers.
