“…The absorption of more global radiation in the still can be achieved by more surface area in the design (Kabeel et al 2019) (Shinde et al 2020). Sharshir et al (Sharshir et al 2020a) experimentally analysed the pyramid still with wick material and nanofluid, it was found that the pyramid solar still with wick material and copper oxide nanofluid has the higher productivity of about 72.95 % whereas for inclusion of wick in the pyramid still has 45 % increase in productivity relative to the conventional pyramid still. Dubey et al (Dubey et al 2021) analysed the environment, energy, exergy and economic for the double slope solar still connected with evacuated tubes.…”

The objective of the work is to investigate the single slope solar still for the enhancement in productivity by the inclusion of optimum weight of palm flower powder of micro-sized in the absorber basin and optimum weight% of micro-Phase Change Material (mPCM) under the absorber basin. In this regard, the effect of different weights of palm flower powder such as 10, 30, 45, 50, 55, 70, 100, 120 and 150 g in the absorber was analysed. The solar still with 50 g of palm flower powder in the absorber increased the productivity by 37.25% whereas, for 10, 30, 45, 55, 70, 100, 120 and 150 g were 11.85, 24.78, 36.1, 36.8, 34.35, 33.05, 10.25 and -20.22% respectively. The effect of different weight% of micro-sized palm flower powder such as 5, 10, 15 and 20 wt%, in paraffin wax, was investigated. The paraffin wax with 20 wt% of micro-sized palm flower powder has a better thermal conductivity of 0.33 W/mK. The experimentation was carried out with 50 g of micro-sized palm flower powder in the absorber basin and 20 wt% mPCM under the absorber basin solar still (PCMPFP-SS) and Conventional Solar Still (CSS). The overall yield of PCMPFP-SS was 4670 ml/m2-day on day 1 and 4250 ml/m2-day on day 2, for CSS it was 3030 ml/m2-day on day 1 and 2800 ml/m2-day on day 2. It was evaluated that the Cost per Litre of PCMPFP-SS was $ 0.025 and $ 0.032 for CSS.

“…A solar still is a typical simple solar device for converting salty or brackish water into drinkable water [53,63]. There are many types ofsolar stills such as pyramid solar still [64,65], solar still with nanomaterials [27,66], tubular solar still [67,68]. A convex tubular SS coupled with wick and nanocomposites was investigated experimentally by Essa et al [69] as shown in Fig.…”

“…27 Although it is difficult to maintain a reduced water depth in the basin' still, researchers have achieved this using the stepped solar stills. 28,29 Several sensible and latent heat storage materials like dyes, gravels, sands, graphite, and phase change materials, are used to store the excess of solar energy during the daytime and to reuse it for maintaining the water temperature at a high level and extend the still productivity during the nocturnal period. 30,31 Nanomaterials are also used as a mixture with brine water to increase the heat transfer characteristics by increasing the thermal conductivity in the basin still.…”

This paper deals with an experimental study performed to evaluate the condenser geometry effect on the natural circulation loop solar still (NCLSS) performance. Three configurations for the external condenser, namely smooth single-tube condenser, finned-tube condenser, and three-tube condenser, were tested under typical summer conditions. The experimental data show that the obtained daily productivity of the NCLSS for the three condenser designs was 2.057, 2.628, and 3.3 kg/m 2 , respectively. The comparison shows that adding external annular fins to the smooth single-tube condenser increases the still's daily productivity by about 27%. The increase in both internal and external areas of the condenser increases the freshwater daily productivity by 60.42% than the smooth single-tube design and by 25.57% than the finned-tube design. The calculations show that the daily thermal efficiency of the NCLSS was 16%, 20.8%, and 25.38% for the three test days, respectively. While, the daily exergy efficiency for the three condenser designs was 1.78%, 2.12%, and 2.22%, respectively.
