Abstract

In this research, the performance analysis of a solar-powered desalination system incorporating a single slope-slope solar still and an evacuated tube solar collector is theoretically investigated. The system comprises a solar evacuated tube that absorbs solar radiation, transferring heat to saline water. This water then flows into a solar still, where it absorbs solar energy, boosting the evaporation rate. Two solar distillers, namely the conventional solar distiller (Still-I) and solar still integrated with evacuated tube solar collector (Still-II), are simulated and analyzed under identical outdoor conditions in Tanta, Egypt. A comprehensive theoretical model, developed using FORTAN programming, simulates the performance of the two distillers and provides insights into the heat transfer mechanisms within the distiller components. Additionally, a comparative energetic analysis of the two proposed distillers is conducted. The simulation outcomes indicate that Still II achieved a notable improvement in freshwater production, recording a 31.26% enhancement (8.02 kg/m².day) compared to Still I (6.11 kg/m².day) under a consistent saline water depth of 2.0 cm. Moreover, the daily energy efficiency was obtained to be 36.00% and 46.72% % for Still I and Still II, respectively.
