Performance of Solar Still Distillation with Paraffin In Tube As Thermal Energy Storage: Experiment and Numerical

Abstract

This study aims to analyze the thermal performance and productivity of a single-slope solar still integrated with paraffin-in-tube thermal energy storage through experimental investigation and computational simulation. The research focuses on evaluating temperature distribution, evaporation–condensation behavior, and freshwater yield using paraffin as the thermal energy medium of the system. The results from both experimental and simulation approaches indicate similar thermal behavior with only slight temperature deviations. The CFD simulation tends to produce slightly higher temperature values due to ideal boundary conditions, whereas the experimental setup experiences natural heat losses through convection, conduction, and evaporation to the surroundings
