A two-dimensional laminar displacement ventilated room with discrete heat and contaminant sources was systematically investigated and the results show that the method provides a simple but practical routine to understand IAE.

• 作者根据室内空气环境的特殊性提出了对流传输与自然模拟方法,简洁有效地分析了二维层流置换通风房间中离散热与污染源之间的相互作用及其对IAE的影响。
