The solar chimney power plant is a relatively new electricity generation concept,\nbased on renewable energy, combining the greenhouse effect with the chimney suction.\nThe solar chimney powerplant consists of three parts, the solar collector, the\nchimney and the turbine generator unit, of which the study was focused on the later\npart. To evaluate the turbine performance inside the solar chimney powerplant, experimental\nsystem was constructed in Aswan, Egypt that has a metrological site\n(23Ã?Å¡58'N and 32Ã?Å¡47'E) occurs. The system was constructed to evaluate the performance\nof the solar chimney turbine and power generation characteristic in the hottest\nsite where Aswan is located at the nearest of the Tropic of Cancer at the summer\nseason. Velocity, electric power generation and the turbine efficiency are studying in\nthis work. The numerical analyses were performed by using a commercial code CFX,\nANSYS 16.1 to simulate the flow through the turbine and overall system. The study\nshows that the range of power generated (1.2 W - 4.4 W). It can be estimated, according\nto the results, the variation trend in pressure drops with the turbine rotation\nspeed increase with small differences when the turbine rotation speed surpasses 1800\nrpm with average efficiency of 57%. It is concluded that the theoretical model is basically\nvalid for the system under study, and the CFD simulation can be used conveniently\nto predict the performance of the system, the comparison between them and\nexperimental result shows a good agreement.
