A comprehensive review on Dish/Stirling concentrated solar power systems: Design, optical and geometrical analyses, thermal performance assessment, and applications

The sustainable transition towards renewable energy sources has become increasingly important nowadays. In this work, a microgeneration energy system was investigated. The system is composed of a solar concentrator system coupled with an alpha-type Stirling engine. The aim was to maximize the production of electrical energy. By imposing a mean value of the direct irradiance on the system, the model developed can obtain the temperature of the fluid contained inside the Stirling engine. The heat exchanger of the microgenerator system was analyzed, focusing on the solar coupling with the engine, with a multiphysical approach (COMSOL v5.3). A real Stirling cycle was implemented using two methods for comparison: the first-order empirical Beale equation and the Schmidt isothermal method. Results demonstrated that a concentrator of 2.4 m in diameter can generate, starting from 800 W/m2 of mean irradiance, a value of electrical energy equal to 0.99 kWe.

Summary The intensity of the solar radiations falling on the earth surface ranges between 5 and 7.5 kWh/m2/day. For the non‐directed solar thermal application, higher intensity level is required. The Concentrating Solar Power (CSP) technology incorporating reflecting mirrors reinforces the solar radiations with high intensity. It is suitable for various applications; that is, space heating, space cooling, and cooking, steam, and power generation without any polluted emissions. Meanwhile, among the various CSP technologies, the Concentrating Solar Parabolic Dish Stirling engine System (CSP‐DSS) has got attention of the research community due to its various attractive features. The output power and efficiency of the CSP‐DSS depend upon their geometrical, optical, and operating parameters. It is therefore, necessary to mathematically investigate the influence of these parameters on system performance before its design and installation. In the existing literature reported, only some specific parameters of the CSP‐DSS have been focused and considered to investigate the system performance. To the best of author's knowledge, no literature has been found to provide the mathematical modeling of all the system parameters in a single manuscript to study and investigate their influence on the system performance. Hence, this review article aims to compile, expansively review and organize the systematical mathematical modeling for all optical, geometrical, and operating parameters of the CSP‐DSS along with the system design methodology. Likewise, the effects of these parameters on the system output power and efficiency under various operating conditions have been investigated. In addition, comprehensive study of CSP‐DSS components along with their classification have been painstakingly discussed to determine optimal system configuration. Finally, the latest review study in the field of CSP‐DSS have been deeply and comprehensively discussed. This review study concludes that, the kinematic gamma type Stirling engine coupled with Permanent Magnet DC generator (PMDC) and Azimuth‐Altitude Dual Axis Tracker (AADAT) could be the better CSP‐DSS design and configuration in context of the standalone off‐grid electricity generation system.

“…The increased level of potable water shortage is robustly related to the industrial revolution, population outgrowth, and increased pollution worldwide (Katekar and Deshmukh, 2020;Kabeel et al, 2021a). Currently, various common distillation technologies are obtainable to tackle the growing of water demand; including humidi cation dehumidi cation (Abdelgaied et al, , 2019aKabeel et al, 2018a), reverse osmosis (Kabeel et al, 2017a), thermal vapor compression (Zayed et al, 2021), multi-effect evaporation (Darwish et al, 2006), multi-stage ash (Lv et al, 2009), solar distillation (Attia et al, 2021a(Attia et al, , 2022, etc. Among these technologies, solar distillation is one of the most promising alternatives for supplying safe water with low energy and freshwater costs (Ahmed et al, 2019).…”

The low energy efficiency of the solar distillers is one of the most key barriers to their effectual usage in the desalination domain. In this work, an experimental investigation was conducted to enhance the freshwater productivity of the hemispherical solar distiller. This was achieved by utilizing flat and v-corrugated iron trays configurations on the bottom of the distiller basin in order to increase the vaporization surface area for better heat transfer of saline water. Three distillers were designed and examined; namely, conventional hemispherical solar distiller (CHSD), hemispherical solar distiller with flat iron trays (HSD-FIT), and hemispherical solar distiller with v-corrugated iron trays (HSD-VIT). Moreover, the effects of using wick materials (WM) in the basin of HSD-FIT and HSD-VIT have been also investigated and compared to that of CHSD. A comparative thermo-economic analysis of HSD-VITWM, HSD-FITWM, HSD-VIT, HSD-FIT, and CHSD has been conducted to determine the better modification that maximizes the performance of hemispherical stills. Experiments were carried out at the desert climate conditions of El-Oued (33°27′N, 7°11′E), Algeria. The results showed that all modifications revealed good thermo-economic performance enhancements and the HSD-VITWM achieved the maximal improvement from both freshwater production and energo-economic performance. The freshwater productivity and energy efficiency of the HSD-VITWM were improved by 83.12 and 81.67%, respectively, relative to CHSD. Additionally, the cost of freshwater production was lowered by 41.72%.
