Abstract

Solar chimney uses solar radiation to trigger the buoyancy-driven flow in the building to allow saturated air inside the building to flow out of the building. At this stage, this research aims to find the optimized geometry for the solar chimney that can be used in Jakarta and display the performance of the optimized solar chimney as one of the solutions for passive cooling. In the present paper, the numerical method investigates the airflow, temperature distribution, and thermal comfort inside the empty room without any human and mechanical activity connected with an inclined solar chimney. RNG k-epsilon modeled the steady-state 3D computational fluid dynamics (CFD) to investigate flow inside the chimney. Discrete ordinate (DO) non-grey radiation model with solar ray tracing is used to simulate heat transfer in the chimney from each time in Jakarta. Chimney geometry parameters were monitored from inclination angle, width, air gap, chimney length, airflow, and average outlet velocity. This research's result is that the optimized solar chimney's optimized geometry is suitable for Jakarta climate and the optimized solar chimney's performance as passive cooling in Jakarta.
