Experimental and theoretical analysis of solar still with solar pond for enhancing the performance of sea water desalination

Abstract

In a practical scenario, only a modest amount of distilled water can be generated each day by a basic solar still with a single basin. Fin-type solar ponds, fin-type solar stills, and integrated fin-type solar stills with finned ponds are investigated. The theoretic performance and experimental studies on the proposed systems were carried out in Pongalur near Tirupur (10.9729° N, 77.3698° E), a region with a latitude of 10° north. Single basin solar still (SBSS), single basin solar still with fin, single basin solar still with pond, single basin solar still with finned pond, and integrated single basin fin-type solar still with a finned solar pond were developed. Adding fins to the small solar pond enhanced the thermal performance of SBSS, by increasing the daily water collection. The pace at which heat is transmitted from the basin to water has risen due to the fins. According to this study, the amount of water collected by single basin solar still with fin, single basin solar still with finned pond, and integrated single basin solar still with fins and finned pond grew by 46, 48, and 52% for each of these systems. HIGHLIGHTS Fin-type solar ponds combined with traditional solar stills are examined in this research.; Amount of water collected by single basin solar still with fin, single basin solar still with finned pond, and integrated single basin solar still with fins and finned pond increased by 46, 48, and 52% for each of these systems.; Both experimental and numerical analysis were done and compared.;
