“…They claimed that the −1 degree convergent-type collector's collector efficiency was 124% higher in winter and 57.4% higher in summer than the horizontal collector. Gitan et al [97] studied the impact of the collector slope on the performance of a possible SCPP system in Malaysian climatic conditions based on the Manzanares pilot facility's geometric measurements. They claimed the highest power output was obtained using a 10-degree collector, which is 3.5 kW more than that of the horizontal collector.…”

This research presents a comprehensive review of solar chimney power plants (SCPP) as a reliable source of renewable electricity generation. Solar chimney power plants differ from other renewable energy technologies because thermal and momentum effects result in 24-h electricity generation. However, they are influenced by a wide range of design, geometrical and operational parameters, and environmental conditions. This review evaluates the design aspects and the theoretical, numerical, experimental, and performance findings in previous works holistically and concisely. The study also extensively discusses the various optimization strategies, advantages, disadvantages, and limitations of solar chimney power plants. Energy storage aspects and hybrid system designs are also addressed in the present review in order to overcome the known handicaps and limitations of solar chimney power plants. The performance figures of the technology are clearly demonstrated as a function of the design and operational conditions, and future prospects are discussed in detail. It is hoped that designers and policymakers will gain valuable insight into the technological features and advancements of solar chimney power plants, assisting them in making a better-informed decision.

“…Patkó et al (2013) Determined theoretically the optimal tilt angle of sun collectors for the four seasons (autumn, winter, spring, summer) [34]. Gitan developed a mathematical model to estimate the performance of (SUPP) based on tracking solar collector consideration and optimize the slope angle of tilted tracking solar collector in Malaysia [35]. Stanciu, C., and Stanciu, D. proposed a numerical simulation of a flat plate collector for the optimum tilt angle at different latitudes from 0° to 80° as β = φ − δ opt function on the latitude (ϕ)and solar declination (δ), [36].…”

“…[5] The solar updraft towers (SUT) are an efficient system to convert solar energy into electricity. [6][7][8] The first step involves converting the solar energy into mechanical energy within the collector. Then, the mechanical energy represented by the airflow is converted into electric energy using a turbine system installed in the chimney.…”

Computational fluid dynamics simulation and optimization of the fluid flow behaviour in a multi‐stage solar updraft tower using a new chimney design

et al. 2023

This work proposes a new chimney design that allows for the development of a multi‐stage solar updraft tower (SUT). The new design consists of two successive divergent chimneys. A 3D model was established to inspect the air flow behaviour within the SUT in six configurations: four multi‐stage systems with four divergence angles of the second stage were compared to the simple conventional SUT and the simple SUT with a divergent chimney. The new SUT performs better than the conventional one, while the two‐stage solar tower multiplied the system efficiency. Two high‐velocity zones appeared for the two‐stage SUT, whereas one zone occurred for the conventional system. The velocity in the two zones achieved a significant value, like that of the conventional system. In addition, the second stage's divergence angle directly impacts the velocity value inside the two stages. The static pressure distribution varies with the change in chimney design. The depression area occurs twice for the multi‐stage SUT in the inlet of each stage.
