Abstract

This study presents a numerical investigation of a solar desalination system enhanced with water film cooling and a flat plate collector. Solar still systems are increasingly recognized as effective solutions for reducing reliance on conventional energy sources in water treatment and for addressing the growing challenge of water scarcity. To this end, three system configurations are analyzed and compared: a conventional solar still (CSS), a solar still with film cooling (SSC), and a solar still incorporating both film cooling and a flat plate collector (SSP). Simulations are carried out under the climatic conditions of Errachidia, Morocco (latitude: 31.91°, longitude: 4.42°). The results demonstrate notable performance enhancements, with daily freshwater yields of 3.48, 4.51, and 8.45 kg/m²·day for CSS, SSC, and SSP, respectively.
