Abstract Influence of area ratio (AR) on main performance parameters solar chimney power plants (SCPPs) is investigated through a justified 3D axisymmetric CFD model. Geometric characteristics Manzanares pilot plant (MPP) are taken into consideration for the numerical AR varied from 0.5 to 10 cover both concave and convex (convergent divergent) designs. Following accuracy verification results p...

The paper examines design and operating data of current concentrated solar power (CSP) 10 solar tower (ST) plants. The study includes CSP with or without boost by combustion of natural gas 11 (NG) and with or without thermal energy storage (TES). The study then reviews the novel trends to 12 produce better ratio of solar field power to electric power, better capacity factor, better matching of ...

A solar-aided coal-fired power plant realizes the integration of a fossil fuel (coal or gas) and clean energy (solar). In this paper, a conventional 600 MW coal-fired power plant and a 600 MW solar-aided coal-fired power plant have been taken as the study case to understand the merits of solar-aided power generation (SAPG) technology. The plants in the case study have been analyzed by using the...

Solar parabolic concentrating collectors are widely and efficiently used in electrical generation. They were experimentally validated in worldwide pioneer plants. SEGS-VI 30 MW solar power plant built in southern California is one of these plants that was commissioned many years ago. In this work a possibility of installing such plant in Makkah, 21.4 °N located in moderate latitudes is studied....

Solar chimneys are devices that use solar energy to generate a hot airflow can be used for power production, the drying of agricultural products, and/or water desalination. The performance small-scale chimney is studied numerically. computational domain includes chimney, ground, and atmosphere. turbulent simulated using commercial CFD code Ansys Fluent. only boundary conditions required simulat...
