EXPERIMENTAL STUDY OF A SOLAR STILL WITH SCREENS IN BASIN

Abstract

The performance of a solar still with different size screens placed in the basin was studied experimentally. The increase in daily production of the still was 11% to 103% compared with an identical still without screens under the same conditions. The effects of screen color, position, number of screens, side wall color, and dye in the basin water were also investigated. An attempt to simulate the new configuration with a simple extension of previous mathematical models for a still without a screen was not successful. This indicates that the lumped formulation used in the analysis of a simple solar still can not be extended to the configuration at hand.
