“…The solar still with the integrated DSS-2 condenser reached the highest efficiency, 47.3%; this still's average efficiency over three days was 46.5%. DSS-2 also has high efficiency compared to previously reported stills with integrated or separate condensers [12,[45][46][47][48][49][50][51][52][53]. This high efficiency cannot be separated from the shape of the condenser, which narrows towards the exit.…”

A solar still requires only two processes: evaporation and condensation. In a solar still, evaporation occurs because of the pressure difference caused by the difference in the temperature of the water and that of the glass cover, while condensation occurs when the water vapour comes into contact with a surface cooler than its dew point. Condensers have been proven to effectively increase the productivity of solar stills. This study aims to compare the efficiency of two developed solar stills with integrated conical condensers to that of a conventional solar still; it also measures the effectiveness of the condenser. Three types of solar stills were used in this study: a conventional solar still (CSS), developed solar still 1 (DSS-1) and developed solar still 2 (DSS-2). All three stills were tested simultaneously. The three solar stills are all made of aluminium with a thickness of 3 mm. The software Ansys Fluent 18.2 was used to analyse the computational fluid dynamics in the stills. The results showed that the efficiency of the CSS, DSS-1 and DSS-2 were 23%, 36.5% and 46.4%, respectively. The freshwater yields of DSS-1 and DSS-2 were, respectively, 1.17 and 1.81 times greater than that of the CSS. These increases in the productivity of DSS-1 and DSS-2 are significantly influenced by the shape of the condenser integrated in these two solar stills; the effectiveness of this condenser was 85.57% and 91.25%, respectively, in DSS-1 and DSS-2. In a simulation, the condenser’s effectiveness was 99.85%.

“…Omara et al (2015) indicated that integration of vacuum fan with an external condenser in corrugated wick SSSS improves the yield by 180% compared to conventional solar still (CSS). Tuly et al (2021) illustrate that the inclusion of condenser in the developed SS enhances the productivity by 10% as compared to the traditional SS. Xie et al (2020) used a 120 W vacuum pump in the SS and arrived a significant improvement in the evaporation and production rate.…”

Purpose The purpose of this paper is to understand the effect of basin water depth towards the cumulative distillate yield of the traditional and developed single basin double slope solar still (DSSS). Design/methodology/approach Modified single basin DSSS integrated with solar operated vacuum fan and external water cooled condenser was fabricated using aluminium material. During sunny season, experimental investigations have been performed in both conventional and modified DSSS at a basin water depth of 3, 6, 9 and 12 cm. Production rate and cumulative distillate yield obtained in traditional and developed DSSS at different water depths were compared and best water depth to attain the maximum productivity and cumulative distillate yield was found out. Findings Results indicated that both traditional and modified double SS produced maximum yield at the minimum water depth of 3 cm. Cumulative distillate yield of the developed SS was 16.39%, 18.86%, 15.22% and 17.07% higher than traditional at water depths of 3, 6, 9 and 12 cm, respectively. Cumulative distillate yield of the developed SS at 3 cm water depth was 73.17% higher than that of the traditional SS at 12 cm depth. Originality/value Performance evaluation of DSSS at various water depths by integrating the combined solar operated Vacuum fan and external Condenser.

 A complete survey on the factors that affect the performance of solar pyramid stills is explained.  Specific categorization of these factors is suggested.  Solar radiation is the strongest affecting parameter on the pyramid solar distiller performance.  Promising future scopes of work on the pyramid solar still is suggested.Due to the rising demand for treated water, the enhancement of potable water yield technologies, such as traditional solar distillers, is a pressing concern. Solar desalination is one of the easiest techniques for producing fresh water from salt water. It has several benefits, not the least. It utilizes free solar energy. Moreover, it is a simple and inexpensive technique compared to other alternatives. They are, nevertheless, relatively inefficient devices. Many studies have been done to boost the daily output of solar stills by using many active strategies to produce a large amount of evaporation and condensation compared to a basic standard type distiller. The magnetic field (MF) is one of the most important and recent techniques affecting the productivity of the solar still due to its positive impact on the water evaporation rate. The primary focus of the current study is to review the effects of magnetic field approaches on the distillate production, performance, and thermal efficiency of several types of solar distillers. Based on previous studies, the magnetic field is responsible for increasing the partial pressure difference between water and glass cover. The change occurs in the hydration shells of the saltwater, which should enhance the evaporation rate and improve the performance of solar still. Besides, the magnetic field significantly reduces the surface tension of salty water, which leads to increased evaporation. Furthermore, the intensity, direction, position, and magnet sizes of magnetic have a strong effect on the rate of water evaporation as well as the rate of heat transfer.
