The solar chimney power plants (SCPP) are thermodynamic devices that transform the heat produced by the solar radiation into electricity. A SCPP make significant contributions to the energy generating in countries where sunlight is available. The optimization of the solar setups is essential to enhance their economic profitability. In this article, a numerical method is investigated by the use of the commercial CFD code Ansys Fluent to analyze the airflow within the solar chimney. Different considered cases have been studied. Indeed, a new design of the SCPP is presented and compared with a conventional solar chimney power plant (CSCPP). The proposed design is characterized by a convergent collector output. For each case, the local flow characteristics were presented and discussed. This technical solution favorite the generated power of CSCPP. This article is identified important to increase the generated power for an existing SCPP.
