READ MORE3.1 Theoretical Analysis 3.1.1 Heat Transfer. In active solar stills, the process of heat transfer takes place through two primary mechanisms, as outlined in [].The first involves the transfer of heat from the water to the inner surface of the glass, while the second mechanism concerns the transfer of heat from the outer surface of the glass to the ambient atmosphere.
READ MOREThe methodologies used in the past years to improve the performance of the active and passive solar stills were reviewed in this paper. Introduction. There is an important need for pure drinking water in many developing countries. Often water sources are brackish (contain dissolved salts) and/or contain harmful bacteria and therefore
READ MOREThe solar still coupled with PTC, FPC, and PLGB, produces more freshwater at a rate of 6.036 kg m−2 during the summer and 2.775 kg m-2 during the winter, according to the results. Furthermore, when compared to conventional solar, FPC-PTC-PLGB solar increased productivity by about 172% in winter and 203% in summer.
