| Abstract | ||||
| In the current study, potential improvements in both flow field and heat transfer characteristics of a prototype solar chimney for power generation through passive flow control approaches have been numerically examined. The numerical modeling was conducted for three different schemes to enhance the velocity magnitude at the entrance of the chimney. The first scheme is concerned with the effect of the number of turbulent generators on the maximum flow speed obtained while the second scheme deals with the effect of throat area at the entrance of the chimney. The last scheme is related to investigating the effect of making round edges having different radii at the entrance of the chimney. | ||||
