A continuous-flow thin-film solar still is analysed. Both fluid dynamics of the thin-film flow and first law analysis of the system are included. A set of equations describing the spatial and temporal variations of water temperature are established and quasi-analytical solutions are presented. A parametric study is conducted to assess the sensitivity of performance to some major variables. It is found that for small water mass in the storage tank steady periodic conditions are established… Expand
