Interest is being shown in the standard solar chimney without collector divergence and in three solar chimneys with three divergence values. The computer simulation was achieved by using the ANSYS Fluent software. The flow characteristics inside all the solar chimney compounds were presented and discussed. An experimental setup of solar chimney was developed to carry out measurements. The results showed that the collector divergence affects the air flow behavior inside the chimney and, consequently, the system performance. The static pressure in the chimney inlet was affected by the collector slope and, consequently, by the velocity value. A comparison between the numerical results and experimental measurements showed good agreement.
