Solar power has gained particular importance in the current era due to a need of harnessing the biggest and cleanest source of energy, i. e., solar energy. One of the most innovative as well as simple technique to generate solar power is using a solar chimney. Solar chimney power plant, however, requires high investment costs and traditionally have been of very low efficiency. Mathematical and CFD models pose a good way to optimize performance of such kind of chimneys. Several factors affect the power generation from a solar chimney including geometric factors (like collector diameter, chimney height) and diurnal temperature variations. The challenge however lies in diurnal variation of temperatures and hence unstable power generation. In the present work, a pilot scale CFD model of solar chimney (of prototype of Manzanares Chimney, Spain, Haaf, 1984) was built and validated with experimental data and analytical models from the literature (∼ <10% deviation from experimental data). Subsequently, flow patterns were studied and a parametric study was carried out for the chimney for the key parameters, namely, chimney height, and collector diameter. For the first time effect of diurnal variations on the power generated was studied. With consideration of diurnal variations, power generation during night was found to be a linear function of chimney height and collector diameter; while, during day time, the power-generated increased exponentially with variation in collector diameter and chimney height.

This study introduces the solar chimney power technology, which is a solar thermal energy system. One of the renewable energy resources, this system is an energy transformation system in which solar energy and wind energy are used together. In this system, the air that is heated with solar energy ensures the production of electric energy by moving upwards with the suction effect of the chimney and rotating the turbine that is placed inside the chimney. In this review, the main principles and characteristics of this system are discussed and the developments on the experimental and theoretical investigations carried out with regard to the solar chimneys around the world especially in recent years are shared with the readers. With the study, it is aimed to provide upto-date information to readers who are interested in this subject.

“…Later, they [15] compared the performance of conventional horizontal-collector solar updraft tower power plants (HCSUTPPs) and SCSUTPPs proposed in China based on simulation. Panse et al [16] developed a model to investigate the performance of the SCSUTPP without a short SUT at the collector top. A mathematical model was developed by Koonsrisuk for the SCSUTPP, and based on this model he studied the effects of a near-unity ratio of the collector inlet flow area and the collector exit flow area, the assumption that the density differences in the collector and that in the chimney are approximately equal, the chimney height and the collector area on the plant performance [17].…”

“…Compared to the solar collector constructed on the horizontal ground, the collector on an appropriate slope at mid and high latitudes will reduce the incidence angle, increase insolation received by the collector, and show higher thermal performance, thus effectively improving the power output of the SCSUTPP. Recently, some researchers [13][14][15][16][17][18] have performed some studies of the performances of the SCSUTPPs by analyzing the air flow and heat transfer in the systems. Cao et al [14] established the mathematical model for SCSUTPP, and took a 5 MW SCSUTPP designed in Lanzhou, China as an example to study the SCSUTPP performance based on their model.…”
