Title: Filtration of an aqueous salt solution in capillary-porous materials in the presence of a phase transition

Abstract

The productivity of portable solar stills is determined to a certain extent by the efficiency of its evaporator, which also performed the function of a capillary-porous wick. As a result of combined filtration and evaporation processes in such apparatus distilled water is produced. With the increase in the density of the thermal flux toward the evaporator surface the output of distillate from the device is increased, but at the same time the salt concentration in the solution increases more rapidly, causing earlier saturation and salinization of the evaporator. The goal of the present study is to investigate the processes of filtration and saturation of an aqueous NaCl solution, the concentration of which varies due to evaporation of water from the surface of the capillary-porous material. Experiments were performed on model wicks with various orientations in the gravitational field.
