Computational fluid dynamics (CFD) simulations were performed for the experiments carried out with two identical pyramid-shaped solar still. One was filled with Jordanian zeolite-seawater and the second was filled with seawater only. This work is focused on CFD analysis validation with experimental data conducted using model of phase change interaction (evaporation-condensation model) inside the solar still. Volume-of-fluid (VOF) model was used to simulate the inter phase change through evaporation-condensation between zeolite-water and water vapor inside the two solar stills. The effect of volume fraction of the zeolite particles (0 ≤ ϕ ≤ 0.05) on the heat and distillate yield inside the solar still was investigated. Based on the CFD simulation results, the hourly quantity of freshwater showed a good agreement with the corresponding experimental data. The present study has established the utility of using the VOF two phase flow model in providing reasonable solution of complicated inter phase mass transfer in solar still.
