Current work presents the application innovative shape of twisted tape including barriers and holes. This disturber device has been installed inside the absorber tube of solar system and such barriers helps to increment of swirl flow and appearance of holes decrease the resistance of fluid flow. Turbulent regime has been presumed for current usage and finite volume technique has been developed for this problem. Involving the hybrid nanoparticles within the water makes the properties of nanomaterial to increase and correlations based of experimental outputs were applied for predicting the features of carrier fluid. Impacts of height of barrier and number of revolution as well as inlet velocity has been depicted in outputs with considering constant value of heat flux over the top surface. Besides, variable heat flux effect has been utilized to show the behavior of system at various time stages of the day. Involving longer barrier makes the swirl flow to rise and temperature of outer wall decreases. As revolution of disturber tape elevates, the residence time grows and stronger secondary flow can be generated.

“…It was observed that the solar still with a modified coating at 20% concentration had the 182 highest improvement in the yield by 34.2% compared to CSS. (El-gazar et al 2021) (Attia et al 2021a) studied the performance of phosphate bags as energy storage material in the solar still. It was 188 found that the cumulative productivity of solar still with energy storage at 1 cm and 2 cm water depth was about 189 5.27 and 4.87 kg whereas the CSS had a yield of 3.8 kg.…”

The proposed research study aims to improve the productivity of solar still (SS) by using low-cost and eco-friendly materials. The aforementioned objective was achieved by enhancing the evaporation rate of seawater in the absorber basin and the condensation rate over the glass cover of the solar still. In this study, the low-cost and eco-friendly materials used for enhancing the evaporation rate in the solar still were Molasses Powder (MP), Sawdust (SD), Rise Husk (RH). In addition to these materials, Bamboo Straw (BS), Banana Leaf stem (BL), and Rice Straw (RS) were used as absorbing materials over the glass cover for enhancing the condensation rate. The experiments were carried out under similar meteorological conditions and the results of the modified solar still were compared with Conventional Solar Still (CSS). The productivities of CSS, SSMP, SSRH, SSSD, SSBS, SSBL and SSRS were about 2250 mL/m2, 2383 mL/m2, 2467 mL/m2, 3033 mL/m2, 2700 mL/m2, 2683 mL/m2, and 3367 mL/m2 , respectively. The results of the experimental investigation highlighted that the SSSD had a comparatively better evaporation rate and 34.81% higher yield than CSS. Besides, SSRS had a comparatively better condensation rate and a 51.88% higher yield than CSS. Later, the combination of sawdust (SD) and rice straw (RS) was investigated for combined enhancement of evaporation and condensation. The solar still with sawdust and rice straw (SSSDRS) showed a 62.88% improvement in productivity with 3633 mL/m2 when compared to CSS. Also, the economic analysis showed that the cost per litre (CPL) of freshwater obtained from SSSDRS was about ₹ 1.9 ($ 0.025) with a payback period of 4.4 months which was the least when compared to all the considered cases.
