This research aims to investigate the Barra–Costantini system’s performance through simulation to obtain the best thermal performance with varying system characteristics, enhance thermal comfort, and reduce energy demand. Three types of glass—single-layer, two-layer, and three-layer—along with various channel dimensions (0.05, 0.1, and 0.15 m) and vent configurations were simulated in a residential building in Mashhad. For a room with a volume of 33.6 m<sup>3</sup>, the maximum heat gained with a 15 cm depth channel and single-layer glass resulted in an energy saving of 29.1%. The room temperature did not exceed 2°C with this system. However, this system alone cannot provide thermal comfort for Mashhad. The level of thermal comfort, as indicated by the Predicted Mean Vote index in October, with and without this system, is –1.6 and –2.06, respectively. Thermal comfort is improved during hot periods of the year by keeping external vents open during the day with an open roof vent at night instead of keeping all vents open throughout the day and night. Additionally, an increase in the height of the Barra–Costantini channel resulted in a decrease in the amount of heat gained.</p>","PeriodicalId":475,"journal":{"name":"Applied Solar Energy","volume":"61 5","pages":"552 - 562"},"PeriodicalIF":1.204,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vortex technologies generate an upward swirling air stream when operating in a moderate temperature range. The conventional air solar collector with a swirling engine is inadequate for creating and keeping updrafts by a previous design. The solar air vortex generator (SAVG) is one of the new alternative energies utilising solar energy to create artificial vortices (AV). The principle of its operation is similar to that of the solar updraft tower (SUT) plan. The research sought to propose, design, and optimise an artificial air vortex generator (AAVG) system by performing a set of calculations using the ANSYS 2024 R1 simulation software. Therefore, there are two aims in this research the first one is the effect of the engine diameter of the solar air vortex generator (SAVG) system in one air inflow slot and the second aim is to study the effect of the number of air inflow slots on artificial air velocity vortex flow behaviour inside the (SAVG) model in single guide blades, these facts were not mentioned in previous studies. Reducing the diameter of the solar air vortex generator (SAVG) system in one slot inflow for [36] by 50% of its dimension can generally increase its kinetic energy, specifically its rotational kinetic energy reaching 1.712 m/s, meanwhile, the results showed that the four slots inflow played a significant role in improving the strength of the generated vortex and increasing its outflow velocity to 5.635 m/s with an enhancement of about 3.5 times of one slot inflow.</p>","PeriodicalId":475,"journal":{"name":"Applied Solar Energy","volume":"61 5","pages":"512 - 528"},"PeriodicalIF":1.204,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147606523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanofluid properties are evaluated for an Al<sub>2</sub>O<sub>3</sub>. Exergy transfer and exergy destruction are calculated for each component. Simulations are carried out for a typical day in March under Dhahran climatic conditions, and the model is validated against published experimental data. The combined configuration with internal reflectors and Al<sub>2</sub>O<sub>3</sub> nanofluid achieves the highest daily water productivity (4.258 L/m<sup>2</sup> day) and daily energy efficiency (52.3%), compared with 2.758 L/m<sup>2</sup> day and 33.9% for the conventional still. The basin liner is identified as the dominant site of exergy destruction. A preliminary economic assessment indicates shorter payback time for the enhanced configurations. Internal reflectors provide the largest performance gains by increasing incident solar energy, while Al<sub>2</sub>O<sub>3</sub> nanofluid offers additional improvement by enhancing internal heat transfer.

Among the various methods of green hydrogen generation, water electrolysis powered by renewable energy stands out as the most environmentally benign approach. This study presents experimental findings and software modeling developed in MATLAB for a small-scale solar hydrogen generation system utilizing proton exchange membrane (PEM) electrolysis. The experiments were conducted in the Ouargla region of southeastern Algeria, characterized by its arid desert climate, to evaluate the system’s performance under real-world conditions. The system integrates two NM 54 polycrystalline photovoltaic (PV) panels, each with a capacity of 250 W, a power control unit equipped with DC-DC converters, and a PEM electrolyzer. Key experimental results revealed that the system produced approximately 295 dm<sup>3</sup> of hydrogen during the trial period. These findings provide a foundational benchmark for scaling up and optimizing hydrogen production systems capable of year-round operation in similar climatic conditions. In addition to the technical analysis, an economic assessment was conducted to estimate the levelized cost of hydrogen (LCoH). Sensitivity analysis highlighted the significant influence of the electrolyzer’s capital cost on the LCoH. The projected results indicate that the cost of producing hydrogen from solar energy in Ouargla is economically competitive, with an estimated LCoH of $8.8 per kilogram of hydrogen.
