Experimental analysis of single-basin solar still with porous fins

Abstract

ABSTRACTThe present research paper explains the experimental analysis of the single-basin solar still with attachment of porous fins on the absorber plate. Here, experiments have been conducted on the single-basin sola still with and without attachment of porous fins. Generally, fins are used in the solar still to reduce the preheating time of water and attain positive water and inner glass cover temperature during morning hours for increment in distillate output. Series of experiments were performed in the Government Engineering College Patan during May 2017 during sunshine hours. Various temperatures such as that of water, inner glass cover and solar insolations have been measured by standard instruments. From the experiment, it was found that the distillate output after attachment of fins was 3.8 L and that of the conventional solar still was 2.67 L. Hence, a percentage increment of 42.3% was found by use of porous fins in a solar still.
