Experimental and numerical evaluation on performance of potable water productivity with rectangular fins basin triangular solar still

Abstract

Demand and conservation for potable water has become a foremost concern world-wide. Many technologies were adapted for converting the saline water to potable water to meet the required demand on water conservation. In the current research work triangular solar still with rectangular-fins attached to the basin is proposed to enhance the output of potable water from the solar still setup. Solar still with and without rectangular-fins on the basin are fabricated for experimental comparison and evaluation in addition to numerical investigations. Thermal Performance, instantaneous efficiency and potable water output of the proposed solar still & base solar still are investigated during March month for the location of Sathyamangalam. Investigation shows enhancement of water production in the proposed solar still by 41% higher compared to the base still. The maximum distillate output from modified still and base still for a typical day is 3.1 liter and 2.2 liter respectively.
