“…Ahmed [17] has reported a continuous increase in output from a solar still with the increase in total solar radiation. Hourly variation of daily distillate output depends upon how the radiation is distributed throughout the day.…”

BackgroundAn experimental work was reported to estimate the increase in distillate yield for a compound parabolic concentrator-concentric tubular solar still (CPC-CTSS). The CPC dramatically increases the heating of the saline water. A novel idea was proposed to study the characteristic features of CPC for desalination to produce a large quantity of distillate yield. A rectangular basin of dimension 2 m × 0.025 m × 0.02 m was fabricated of copper and was placed at the focus of the CPC. This basin is covered by two cylindrical glass tubes of length 2 m with two different diameters of 0.02 m and 0.03 m. The experimental study was operated with two modes: without and with air flow between inner and outer tubes. The rate of air flow was fixed throughout the experiment at 4.5 m/s. On the basis of performance results, the water collection rate was 1445 ml/day without air flow and 2020 ml/day with air flow and the efficiencies were 16.2% and 18.9%, respectively.FindingsThe experimental study was operated with two modes: without and with air flow between inner and outer tubes.

“…Their study showed that still output varies between 0.5 and 2.5 kg m À2 for the fabric surface sponges. The effect of the use of an internal condenser on the performance of a solar distiller was investigated experimentally by A.S. Ahmed [14]. Their results showed that the combination of an internal condenser with the solar distiller improved the performance of a distiller.…”

“…Their research demonstrated that if the surface were covered with wet cloth rather than the ambient temperature, the water produced would increase. Ahmed evaluated the effect of utilizing a cooler in a single‐stage solar still. He presented his results in two cases with and without cooler, indicating that a cooler use would raise the water production from 5.5 to 5.9 kg/m 2 .day.…”

Summary In the present experimental research, a five‐stage solar still was investigated using phase change material paraffin wax. Owing to Iran's climatic conditions and its location in a dry area and nonexistence of fresh water sources, producing this water from saline water sources is essential. In this research, thus, a multistage solar still was planned and examined as a commonly used freshwater source via (phase change material) paraffin wax. On the back of the collector absorber plate, paraffin wax (phase change material) was used as an additional energy source for the sun. The volume of water produced in different thicknesses of 2.5 cm, 5 cm, and without PCM was investigated. The study results specified that the application of phase change material paraffin wax in the thickness of 2.5 cm agent led to a 15% increase in freshwater production. The quantity of water generated in the flow rates of 0.7, 1.3, and 1.8 L/min was also studied. The highest quantity of water produced was obtained in the 1.3 L/min flow rate. Moreover, the quantity of water generated in the five stages of the desalination process was separately measured that the highest amount of production was associated with the first stage.
