“…It is concluded that system productivity is enhanced by 18% and 27.6% when vertical and inclined fins are used. Sathyamurthy et al 46 have carried out a theoretical and experimental study of TSS with and without fins. Fins in the TSS basin increased the amount of heat absorbed by the absorber basin due to the high surface area of the absorber plate, resulting in higher freshwater output than TSS without fins.…”

Access to safe drinking water remains a global challenge, primarily due to the prevalence of water contamination in various regions. Numerous methods have been explored to address this issue and convert polluted water into potable sources. However, the cost associated with these methods often hinders their widespread adoption. Solar distillation, harnessed by abundant solar energy, emerges as a promising and sustainable solution. Although solar distillation technology has made significant advancements in recent years, the endeavor to boost its efficiency remains a substantial challenge. Typically, solar stills yield between 4 and 6 liters of fresh water per square meter of solar still per day under ideal circumstances. Notably, both single‐basin and double‐basin solar stills have been extensively researched to discover methods for enhancing their productivity. A notable innovation in this field, the tubular solar still (TSS), has gained recognition for its capacity to improve productivity. The present review article systematically examines the development of efficient and cost‐effective solar distillation systems on a global scale. It provides a comprehensive analysis of the literature pertaining to techniques employed to enhance TSS performance. The study categorizes these techniques, conducts in‐depth evaluations of both experimental and simulation studies, and offers a meticulous comparison of various strategies to optimize TSS functionality. Furthermore, the article identifies existing research gaps and puts forth prospective directions for advancing TSS efficiency.

“…The maximum enhancement of the freshwater productivity was 67.1% and obtained for wood thickness of 4 mm and nanoparticles concentration of 80 g/m 2 . Sathyamurthy et al 9 enhanced the performance of a TSS by using fins fixed along the trough transversely. They reported 22% enhancement in the hourly freshwater productivity while 2% and 7% for exergy and energy efficiency, respectively.…”

The aim of this work is to explore the thermal performance of a tracked tubular solar still (TSS) with a parabolic trough concentrator in Baghdad (33.27° N, 44.37° E) in September 2022. The present tubular still is distinguished by its hexagonal glass cover. The effect of integrating the TSS with a heat pipe, the still tilt angle (10°, 15°), and the depth of saline water inside the still partitions on the productivity of freshwater are investigated. The results showed that using heat pipe enhances the freshwater productivity by 25%–40% and the efficiency by 25%. For the still integrated with heat pipe, as the water depth is increased from 5.5 to 6.5 cm the productivity of freshwater is increased by 16% and 20% for tilt angles 10° and 15°, respectively.
