ABSTRACT

Solar Updraft Towers (SUTs), also known as solar chimneys, are innovative renewable energy systems that harness solar radiation to generate electricity. This research aims to enhance our understanding of the fluid dynamics within solar chimneys, facilitating more efficient and sustainable energy generation from this promising technology. CFD simulations are conducted to investigate the behavior of air currents within the SUT and the resulting power generation efficiency. Investigates the interrelationship between chimney height and collector diameter, to evaluate their impact on the solar chimney’s performance. Two diameter chimneys are model and analyzed that is 23 mm and 66 mm for various heights. Results demonstrate with increase of tower height will increase the velocity of air and power generation. The findings contribute to the ongoing efforts to optimize SUTs as a clean and renewable energy source. Numerical solutions are compared and are in good agreement with experimental data.
