Summary: | With annual increases in energy demand, solar chimney power plants
(SCPP) are regarded as one of the renewable energy power plants. It can
potentially be an alternative renewable energy source such as photovoltaic
(PV) cells and wind when properly developed. This study primarily focuses
on determining the optimal size of a SCPP by examining various
geometrical characteristics of the SCPP. The approach for this investigation
included utilizing Computational Fluid Dynamics (CFD) to simulate the flow
within the SCPP. Three essential parameters were examined in this
investigation: the chimney’s height, its diameter, and the shape of the
SCPP’s solar collector. The model was developed using 3D visualization
tools, and the results were validated to demonstrate that it fulfils the
degree needed for the model’s intended purpose or application. In
addition, the simulation was used to investigate the temperature and air
velocity of the SCPP. It was discovered that increasing the chimney height,
decreasing the diameter of the chimney, and utilising a square collector will
help improving the SCPP’s performance. By expanding the chimney height,
the temperature and air velocity will be higher, but the air velocity
decreases after exceeding 4.0 m of chimney height. The optimal diameter
shows at 16 cm when both temperature and air velocity are at their
maximum values. In contrast, the air velocity generated by the square
collector is more than the air velocity produced by the circular collector. In
order to improve simulation results, it is recommended to cross-reference
with experimental data specifically. |
