Numerical analysis for enhanced water desalination in solar stills with optimized glass cover angles. Journal of Advanced Research in Numerical Heat Transfer, 22(1), 31-45. 10.37934/arnht.22.1.31452735-0142https://hdl.handle.net/20.500.12939/4839Water scarcity is a growing global issue that necessitates improved desalination techniques. This study aims to enhance solar still efficiency for water desalination in Baghdad's climate conditions. The research focuses on identifying the optimal glass cover tilt angle to maximize water production in single-slope solar stills. A multi-software approach was implemented, using SOLIDWORKS for design, ANSYS CFD for simulations, and MATLAB for numerical analysis. The solar still's performance was tested on July 25, 2023, from 9 AM to 5 PM, with tilt angles between 25° and 40°. Results show that a 25° angle is most effective, increasing water output by 3.3% compared to other angles. This optimal angle enhances solar radiation absorption while maintaining efficient condensation. Temperature distributions and evaporation rates were also analyzed to support these findings. These results provide valuable insights for optimizing solar still designs in regions with climate conditions similar to Baghdad, contributing to the development of more efficient water desalination technologies for water-scarce areas.eninfo:eu-repo/semantics/openAccessAlgorithmsNumerical analysisOptimizingSolar stillThermal analysisArticle22131452-s2.0-85201829600Q1
