Abstract
In this study, effects of the contractions of the inlet and outlet areas of a vertical solar
chimney were examined with a Computational Fluid Dynamics. The results show that the flow
rate decreased with both the inlet and outlet areas. The outlet area influenced more than the inlet
area did. The flow rate decreased linearly with the outlet area, however, was affected
significantly only when the inlet area was below half of the air gap.
