“…The work reported a 139% increase in turbine efficiency with the introduction of guide vanes [11]. The authors suggested that adding the guide vanes increases the mass flow rate of air and the turbine shaft power due to the guided fluid flow towards the turbine region [11]. The studies conducted previously suggested turbine performance improvement with the use of real turbine models and guide vanes.…”

With the uprise in global population and rapid industrialisation in developing nations, increasing energy demand to compensate for societal and industrial needs is inevitable. However, popular energy resources such as gas, petroleum, and coal, on which the global energy mix is heavily reliant, induce environmental pollution and global warming. Thus, clean energy sources, such as wind and solar, are increasingly sought to mitigate these adverse environmental effects and identify alternative sustainable and renewable energy technologies. The existing literature suggests minimal research has been conducted on the turbine component of the solar chimney power plant (SCPP). The present research proposes the study of a vertical axis wind turbine (VAWT), namely the Savonius-style wind turbine (SSWT), for power augmentation in the SCPP under the influence of guide vanes and shields that are installed in the solar collector area. A two-dimensional numerical analysis is performed using the ANSYS Fluent software. The SSWT and SCPP models used in the simulations were validated using numerical and experimental results from previous literature data. The angle of the guide vanes was varied while the dimensions of the SCPP model and the energy extractor considered were kept constant. The optimum turbine performance was identified based on the flow analysis and the power output of the rotary component from different guide vane configurations. The present study shows an overall improvement in the turbine’s performance coefficient and power output under the influence of the guide vane and shield in the SCPP. The turbine with the guide vane and shield at an angle of 45° enhanced the performance by 22.22% and power output by 22.25% compared to the turbine without the guide vane and shield.

“…However, due to the low energy conversion efficiency of an SCPP, some innovative SCPP hybrid systems have aroused the interest of researchers. These novel SCPP systems have been applied in various fields, including freshwater generation from air [24,25], alleviating the problem of urban air pollution [26][27][28], desalination of seawater with a modified SCPP [29,30], and improving the partial climate [31,32].…”
