本研究分析台湾地区传统厨房的通风效率与室内空气品质，其中以不同孔隙率的屏风取代传统厨房的横梁。通过数值模拟和室内实验研究了多孔屏风对厨房内温度场、流场和通风量的影响。采用示踪气体浓度衰减法测定了厨房内空气的换气率和老化程度。同时，进行计算流体动力学（CFD）分析，以获得详细的了解温度和流量分布。
This study analyses the ventilation efficiency and indoor air quality of conventional kitchens in Taiwan, in which the transoms were replaced by screens of various porosities. Numerical simulations and full-scale laboratory experiments were performed to investigate the influence of the porous screens on the temperature fields, flow fields and ventilation rates within the kitchen. The tracer-gas concentration decay method was applied to measure the air exchange rate and the age of the air in the kitchen. Meanwhile, computational fluid dynamics (CFD) analysis was performed to obtain a detailed understanding of the temperature and flow distributions.
