Abstract

A solar chimney is a one source used newly in power generation by converting solar energy to kinetic energy. One of the limitations of using a solar chimney is the availability of large areas for building the chimney system to obtain sufficient kinetic energy at the chimney entrance. Addressing spatial constraints in chimney systems, this study pioneers an innovative approach to augment energy generation within existing footprints. By integrating swirl guide blades into the collector, the air movement path is extended, resulting in an increase in energy at the chimney entrance. Rigorous examination of four swirl guide blade configurations is conducted through advanced numerical simulations, employing the CFDRC code with a structured grid. In addition, the study meticulously investigates the impact of collector diameter variations on overall system efficiency. Finally, the selected best configuration was studied at different numbers inside the collector. The results showed an increase in average velocity at the chimney entrance and system power of 115.1 % and 30.2 % using eight guide vanes, respectively.
