Experimental and Theoretical Performance of Mini Solar Chimney Power Plant

Abstract

Abstract-Electricity production generated by sufficient amount is a critical issue over the entire world. The global warming is another critical issue. Currently, renewable energy sources are ones of the most important solutions to deal with these two issues. Aswan city is one of the hottest and sunniest cities in the world. This climate conditions makes the city an ideal place for Solar Chimney Power Plant (S.C.P.P) to produce electrical energy. In this study, a very small model of chimney height of 6m, collector diameter of 6m and chimney diameter of 0.15m is installed. The mathematical model which is based on the thermodynamic analysis of the flow inside the SCPP, is used to predict its performance .The experimental performance and the theoretical one-calculated from the mathematical model-are found to be in a good agreement. This model is used to predict the output power of a bigger model of 20m chimney height, 30 m squared collector and 1m chimney diameter which is still under construction. The results show that the bigger model can produce a theoretical power of about 600 hundreds times the smaller one. This study helps in selecting the generator power for the bigger model.

A genetic programming approach for the prediction of solar chimney power plant power

“…The power calculation of SCPP systems has been performed with experimental Accelerometer temperature change error 0.5 measurements in the literature. [9][10][11][12][13][14][15][16] In the design parameters of these systems, parameters such as chimney height, collector area, and chimney diameter show differences. For this purpose, in order to compare the calculated and estimated power parameters in this study, and the results were compared in Figure 7.…”

“…Therefore, when developing large-scale solar chimney systems, the actual performance data of the prototype should be taken into account and more detailed studies should be carried out. 14 Jemli et al (2017) found out in their experiments, an average of 0.3 W/m 2 of electrical power could be generated on a solar chimney prototype assembly with an 8-meter-diameter collector and a 2-meter-high tower. In addition, the temperature distribution of the prototype at different angles and the electrical energy generated were also quantified.…”

“…Thus, solar energy systems can be made more economical, efficient, and sustainable. 13 In their study, Mekhail et al (2017) developed a prototype solar chimney system with a height of 6 m and a collector diameter of 0.15 m. They used this prototype to estimate the output power of a model with larger dimensions. The larger model was considered to have a height of 20 m, a collector area of 30 m 2 and a chimney diameter of 1m.…”

Analytical and Experimental Investigation of the Solar Chimney System

“…Kasaeian et al [5] presented a comprehensive review of solar chimney systems. Depending on the research directions, solar chimneys may serve various goals [6][7][8][9], such as natural ventilation in the buildings [2,5,[10][11][12][13], small-scale power plants, generation in full-scale energy generation systems, and some applications in smart islands [14][15][16][17][18].…”

“…A power plant consisting of a solar collector and a chimney can work as a solar thermal power plant [6,7,[18][19][20][21][22][23][24][25], which first converts solar energy into thermal energy in the solar collector to further convert it into kinetic energy in the chimney, with final electricity generation by applying a wind turbine and generator [14,16,26]. The construction of such a solar chimney may depend on the shape and dimensions of both the collector and chimneys and their canopy profiles [10,27].…”
