The solar chimney power plant (SCPP) is designed to produce electricity from solar radiation. A chimney solar power plant is generally equipped with one or more turbines designed to say no to plagiarism. Get a tailor-made essay on “Why Violent Video Games Should Not Be Banned”? Get an original essay to extract kinetic energy from wind flowing upward due to natural convection. Then, the generator, coupled with the turbine, converts the kinetic energy of the wind into electrical energy. Several researchers have reported that the use of chimney solar power plant is an encouraging solution to produce electrical energy. Optimization of the solar installation requires the study of geometric parameters such as the diameter of the collector, the height of the roof of the collector [1], the height of the chimney [2], the diameter of the chimney, the inclination of the roof [3] and the design of the turbine. The first prototype of the SCPP was built in Manzanares. The prototype is characterized by a height equal to 194.6 m and a collector radius equal to 122 m. In this context, Haaf et al. [4-5] developed the preliminary test results of SCPP. They presented the energy audits, the efficiency values ​​of the collectors, the pressure losses due to friction and the losses in the turbine section. Ayadi et al. [3] developed a numerical model to evaluate the performance of chimney-powered solar systems while varying the collector roof angle. The authors reported that the efficiency of the chimney solar power plant increases with a negative collector roof angle. Xu et al. [6] numerically analyzed the influences of solar radiation and pressure drop across the turbine on the power output of the chimney solar power plant. From the literature, researchers have reported some configurations of turbine configurations such as single rotor turbine without inlet guide vanes (IGV), single rotor turbine with IGV, counter-rotating turbine without IGV and counter-rotating turbine with IGV. The turbo-generator of the Manzanares prototype was designed by Schwarz and Knauss [7]. The authors proposed a single rotor configuration without guide vanes. Later, Gannon and Von Backström [8] carried out an experimental analysis of the performance of chimney solar turbines. It was reported by the authors that total-to-total efficiency and total-to-static efficiency are equal to 85-90% and 77-80% respectively over the conceptual range. Another work was presented by the same authors [9] to develop analytical equations making it possible to define the impact of each coefficient on the efficiency of the turbine. Recently, Ming et al. [10] carried out a numerical simulation for a chimney solar power plant coupled with a five-blade turbine. The considered system is characterized by a chimney height equal to 400 m, a chimney radius equal to 30 m and a collector radius equal to 1500 m. The authors presented the impact of turbine rotational speed on the average stack exit velocity, average stack exit temperature, pressure drop across the turbine, and system mass flow rate. The maximum power generated and the efficiency of the turbine are approximately 10 MW and 50%, respectively. Guo et al. [11] presented a 3D numerical simulation of a solar chimney coupling with a turbine. In their work, they varied the rotational speed of the turbine to study the optimal operating condition of the turbine. In their study, they took into account the influences of the angle of incidence of sunlight. The results revealed that the hourly variation of the sun's zenith angle is a.
