摘要：
This study analyzes the ventilation efficiency of a bedroom with a wall-mounted center-pivoting window. Numerical simulations and experiments were performed to investigate the airflow and the pollutant distribution in the bedroom. The air exchange rate and the carbon dioxide concentration profiles were investigated for various window opening angles and inlet wind velocities. The computational fluid dynamics analysis and experimental results presented provide a comprehensive understanding of the typical natural ventilation characteristics of a wall-mounted center-pivoting window in a bedroom of a typical home in Taiwan.
