Numerical Study of a Basin Type Solar Still with a Double Glass Cover Under Winter Conditions

Abstract

A numerical analysis of a basin-type solar still with a double glass cover is done under winter circumstances of solar radiation, ambient temperature, and wind speed. Equations defining thermal balances of different components of traditional and double glass cover solar stills are used to describe the physical issue, which is then solved using the Gauss-Seidel numerical technique. The effects of solar radiation, ambient temperature, and wind speed on the daily production, internal efficiency, and overall performance of solar stills are calculated and illustrated. The findings demonstrate that a solar still with a double-glass cover is more productive and efficient than a solar still with a single glass cover.

A comparative numerical study of three similar passive solar stills: Single slope, V-type, and greenhouse

“…Depending on the layout of the glass covers, the double slope still includes two kinds: V-type and greenhouse. Studying the configurations of passive solar distillation remains a great interest of scientists to improve its productivity [4][5][6][7].…”

“…Analytical and experimental research for V-type solar still was done early [8,9]. However, a numerical investigation to analyze the heat and mass transfer phenomena in the still enclosure has not been found.…”

Conical Solar Distiller Performance with Different Aspect Ratios

“…The authors' study is notable because it demonstrates the advantages of using active approaches and increasing the number of stages in sun stills to increase the rate of evaporation and condensation when compared to standard solar stills. Figure a, shows a schematic representation of several solar still arrangements [17], [18].…”
