The solar chimney power plants produce electricity and thermal heat using the solar radiation. The thermal study of the solar chimney power plants is required since these systems are characterized by their high costs. This paper focuses on the study of a solar chimney power plant coupled with a turbine to increase the generated power. Thus, four turbine diameters are proposed. For each configuration, the distribution of the magnitude velocity, the air temperature, and the pressure was discussed. The results indicate that the generated power increases with the increase of the turbine diameter. This technical solution is identified interesting for designers to increase the generated power.
