Performance of a solar chimney configuration to achieve equal flow rate for ventilation of three-story building

In energy-efficient buildings, natural ventilation using solar chimneys greatly reduces energy consumption. In this study, a solar chimney was installed in a three-story building to examine the flow rate of the floors while balancing the flow rate of each floor. To predict the flow rate, a fluid dynamics model was developed based on a computational fluid dynamics (CFD) method with a calculated model of RNG k-e, heat flux 600 W/m2. By changing design parameters, the air flow was investigated.
