Abstract
This chapter presents the modeling and the experimental study of a water
solar collector coupled to an optimized solar still developed in order to boost
freshwater production 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 of the water solar collector. The obtained set of ordinary differential
equations was converted to a set of an algebraic system of equations by the functional
approximation method of orthogonal collocation. The aim of this study is to present the
mathematical model and experimental study of this water solar collector.
