Özet
This paper discusses the three-dimensional numerical study of a new finned collector integrated into the solar chimney power plant. Manzanares pilot's details, which are tower height 194.6 m, rooftop height 1.85 m, rooftop diameter 244 m, tower diameter 10.16 m, and pilot mean temperature 20 degrees C with air speed 15 m/s, are implemented in this work to check the suitability of the finned collector as a way of improvement. In order to assess the unique idea, a parametric study is done with different number of fins: 46, 33, and 25; different fin widths: 0.5, 0.25, and 0.1 m, and different fin heights: 1.2, 0.925, and 0.6 m. Therefore, optimal outputs could be obtained by the novel rooftop that is proposed in this study, where the efficient case is specified dimensionally by 46 fins, a fin width of 0.1 m, and a fin height of 1.2 m, which gives 1.674% as the station performance, 700.597 kW as the resulted power of the plant, 1790.3 as the Nusselt number, and 1.96E+14 as the Rayleigh number.
