“…q e,w−g = 0.01623h c,w−g P w − P g (10) The entire rate of internal heat energy transfer between raw water and basin inside glass cover is, as a result, computed as the total effects of all the three kinds of heat transport variations-by convection (q c,w−g ), by radiation (q r,w−g ) and by evaporation (q e,w−g ). Following is the mathematical expression: q t,w−g = q c,w−g + q r,w−g + q e,w−g (11) The total rate of heat energy internally transferred can be alternatively computed as a function of the overall coefficient of internal heat transfer and temperatures of both salty water and the inner face of the glass cover, as illustrated in the following formula: q t,w−g = h t,w−g T w − T g (12) For the above equation the value of the overall internal heat transfer coefficient transfer (h 1 ) taking place between salty water surface and the inside of the glass cover can be mathematically determined based on the following algebraic equation [60]:…”

In the face of an escalating global water crisis, countries worldwide grapple with the crippling effects of scarcity, jeopardizing economic progress and hindering societal advancement. Solar energy emerges as a beacon of hope, offering a sustainable and environmentally friendly solution to desalination. Solar distillation technology, harnessing the power of the sun, transforms seawater into freshwater, expanding the availability of this precious resource. Optimizing solar still performance under specific climatic conditions and evaluating different configurations is crucial for practical implementation and widespread adoption of solar energy. In this study, we conducted theoretical investigations on three distinct solar still configurations to evaluate their performance under Baghdad's climatic conditions. The solar stills analyzed include the passive solar still, the modified solar still coupled with a magnetic field, and the modified solar still coupled with both magnetic and electrical fields. The results proved that the evaporation heat transfer coefficient peaked at 14:00, reaching 25.05 W/m 2 .°C for the convention pyramid solar still (CPSS), 32.33 W/m 2 .°C for the magnetic pyramid solar still (MPSS), and 40.98 W/m 2 .°C for elecro-magnetic pyramid solar still (EMPSS), highlighting their efficiency in converting solar energy to vapor. However, exergy efficiency remained notably lower, at 1.6%, 5.31%, and 7.93% for the three still types, even as energy efficiency reached its maximum of 18.6% at 14:00 with a corresponding peak evaporative heat of 162.4 W/m 2 .

“…Choosing an optimal location is influenced by the availability of sunlight, local climate conditions, and proximity to water and salt sources. Ideal sites have high solar insolation, minimal precipitation, low wind speeds, and stable geological conditions to support the structural integrity of the pond (Rghif et al, 2023). Proximity to necessary resources like water and salt can significantly reduce operational costs and logistical challenges.…”

In recent times, renewable energy resources have been greatly researched because of the increasing concern to minimize global warming and meet energy demands. Energy storage systems have become useful tools for sustainability and meeting energy needs. Solar energy has proven in recent times to be the primary and most prevalent option due to its environmental friendliness, availability, and minimal pollution. Effective utilization of available energy resources has led to developing new alternative energy devices like the solar thermal energy storage system (STESS) with a solar energy source. Solar thermal energy systems are efficient systems that utilize solar energy to produce thermal and electrical energy. This review aims to give a detailed overview of solar TESS, different TES application systems, and effective methods of increasing the system performance to provide energy during deficient times. The various classifications, basic components, the principle of operation, application areas of STESSs, prospects, and extensive reviews on these aspects have also been discussed in this review. The different factors to be considered geared towards meeting energy demands and increasing the efficiency of solar TES systems have been duly detailed. This review is a single manuscript with a detailed overview of STESS, the principle of operation and components of STESS, thermal energy storage materials, a description of different application systems, and a discussion of factors responsible for improving the system efficiency.
