Performance analysis of snail shell biomaterials in solar still for clean water production: nature-inspired innovation for sustainability.

In this current investigation, the experimental performance of a solar still basin was significantly enhanced by incorporating snail shell biomaterials. The outcomes of the snail shell-augmented solar still basin (SSSS) are compared with those of a conventional solar still (CSS). The utilization of snail shells proved to facilitate the reduction of saline water and enhance its temperature, thereby improving the productivity of the SSSS.

Performance evaluation of external compound parabolic concentrator integrated with thermal storage tank for domestic solar refrigeration system.

The aim of this research was to develop a model for a solar refrigeration system (SRS) that utilizes an External Compound Parabolic Collector and a thermal energy storage system (TESS) for solar water heating in Chennai, India. The system parameters were optimized using TRNSYS software by varying factors such as collector area, mass flow rate of heat transfer fluid, and storage system volume and height. The resulting optimized system was found to meet 80% of hot water requirements for the application on an annual basis, with an annual collector energy efficiency of 58% and an annual TESS exergy efficiency of 64% for a discharge period of 6 h per day.

Comparative study of double-slope solar still, hemispherical solar still, and tubular solar still using AlO/water film cooling: a numerical study and CO mitigation analysis.

Solar still, as one of the important devices for generating water using renewable energy, has been widely used in arid as well as coastal areas where access to fresh water is limited. This paper uses CFD simulation to compare double-slope solar still, hemispherical solar still, and tubular solar still using nanofluid film cooling. AlO-water nanofluids with a concentration of 0.

Thermodynamic and economic analysis of heat pump-assisted solar still using paraffin wax as phase change material.

In this research, the thermodynamic (energy and exergy) and economic assessments of heat pump-assisted solar still with paraffin wax was investigated under the climatic conditions of Coimbatore city in India during the year 2020. The observed experimental results in heat pump solar still (HPSS) was compared with conventional solar still (CSS) in the same climatic conditions. This model works on the principle of latent heat observed during condensation which was regenerated by heat pump to preheat the inlet basin saline water of solar still.

Augmentation of freshwater productivity in a single-slope solar still using ball marbles.

In the current research, the energy and economic performance in single-slope solar still using ball marbles (BMSS) has been investigated and compared the results with conventional solar still (CSS) under the similar weather conditions of Karaikal (10.92° N, 79.83° E), India, during October 2020.

Performance analysis of crushed gravel sand heat storage and biomass evaporator-assisted single slope solar still.

In this research work, the productivity, energy, exergy, and economic and enviro-economic performance in crushed gravel sand heat storage and biomass evaporator-assisted solar still (CGS-BSS) have been investigated and compared the results with conventional solar still (CSS) under the similar climatic conditions of Coimbatore City during the year 2019. The heat accumulated in crushed gravel sand and biomass evaporator have been used to preheat the inlet saline water and air vapor before entering into the solar still. This results in enhanced air vapor mixture temperature and evaporative heat transfer rate of CGS-BSS significantly.

Assessment of single slope solar still using block and disc magnets via productivity, economic, and enviro-economic perspectives: a comparative study.

In this research, the productivity, economic, and enviro-economic analysis of single slope solar stills using block magnets (BMSS) and disc magnets (DMSS) were performed under the climatic conditions of Coimbatore city (latitude, 11° 01' 68″ N, and longitude, 76° 95' 58″ E), in India, 2019. The results observed in BMSS and DMSS were compared with conventional solar still (CSS) under the same climatic conditions. The usage of block and disc magnets in basin of solar still was improved the daily productivity significantly.

Performance improvements of single slope solar still using graphite plate fins and magnets.

In this paper, the performance of a single slope solar still has been improved using graphite plate fins and magnets (GPF-MSS) in the basin and compared with conventional solar still (CSS) under the same climate conditions. The experiments have been carried out at Coimbatore city in India during the summer months of 2019. The energy and exergy performances of solar stills have been assessed under the influence of solar irradiation, ambient temperature, and wind velocity.
