“…The performance of a solar chimney is closely related to the solar radiation and to the ambient temperature at the collector inlet . The first interest was the injection of the exhaust gas into the collector inlet, where three cases studied were as the following: 25%, 50% and 100% flow of the burned injected gases.…”

“…Several studies were conducted on the solar chimney to reduce the cost of kWh , either by increasing the geometric parameters or by steering towards hot areas with large solar radiation . Other studies were interested in slipped system or in the heat transfer , but the cost is still high compared to the thermal and nuclear energies because of their availability.…”

It has been observed during the production process of a solar chimney that the ambient temperature at the collector inlet is the main reason for the system weakness. In this paper, an improved design concept depending on coupling a solar chimney with a gas turbine has been presented. Here, increasing the efficiency and reducing the specific costs (€/kWh) of the solar chimney power plant are the main purposes of this study. The exhaust gas of the turbine will be injected either at the inlet or the middle of the collector, which allows a quick increase of the efficiency and recovering the energy from the exhaust gas. For conducting the numerical simulations, the Fluent software will be used. The results showed that in the present method the velocity at the inlet of the chimney and the outlet of the collector increases together with the temperature to high values. This increases in turn the power production rate till ten times (from 50 to 500 KW). Consequently, the specific costs will be greatly improved. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1160–1168, 2018

“…While Dai et al [4] carried out a study to build a power station in villages in northwest China, with dimensions of 200 m height of the chimney, a diameter of 10 m, and a collector diameter of 500 m, which can produce a net output of 110 to 190 KW of electric power throughout the year. On the other hand, Djimli et al [5] examined the installation of a solar chimney power plant in the region of M'Sila (Algeria) with the same prototype characteristics of Manzaneres (Spain), to produce a net output of 39 to 72 kW. In addition, the same authors [6] carried out a second investigation on the possibility of installing a solar chimney power plant across the national territory of Algeria (Algiers, Batna, Bechar and Ghardaia).…”

This work offers the opportunity to consider the possibility of realizing a solar chimney power plant in the region of Constantine (Algeria). This region is characterized by its important solar radiation resource and ambient temperature. Based on actual measurements of Constantine weather station for the period of April 2020, the performance analysis of a solar chimney which have three times the dimensions of the Manzaneres prototype (Spain) is carried out using of Fluent software. The obtained results show that when the dimensions of the solar chimney are large, the impact of small changes in solar irradiation is negligible. Also, the studied power plant with dimensions of; 584 m height, a diameter of 30 m and a collector diameter of 732 m is capable of producing a monthly average of 72 to 296 MW of electrical energy, this energy production would be sufficient to meet the needs of rural areas located in this region.

The main objective of this work is to make the numerical analysis of velocity fields and temperature (heat transfer) in a solar chimney with different numbers of Rayleigh. The problem is to study natural turbulent convection in a tow dimensionless system, with well-defined boundary conditions. The results obtained, for the different studied cases, are compared to show the influence of various parameters. Particular attention is paid to the velocity profiles and to horizontal and vertical temperature inside the chimney. The Fluent software was used.
