Modeling and Experimental Study of a Water Solar Collector Coupled to Optimized Solar Water Still

Abstract

This work presented the modeling and the experimental study of a water solar collector coupled with an optimized solar still developed in order to boost fresh water produced in a solar distillation system. The desalination process is currently operated under the climatological conditions of Sfax, Tunisia. To numerically simulate the water solar collector, we developed a dynamic model based on heat and mass transfer from the water solar collector. The obtained set of ordinary differential equations was converted to a set of algebraic system of equations by the functional approximation method of orthogonal collocation. The aim of this study was to present the mathematical model and experimental study of this water solar collector
