| 摘 要： | 以计算流体力学和传热学为基础,利用FLUENT软件建立了四种典型气流组织形式的物理及数学模型,运用Κ-ε模型对室内气流组织进行了三维数值模拟.对各种气流组织形式下建筑物室内的流场、温度场及浓度场的数值模拟结果进行分析比较.结果表明:置换通风在温度场、速度场、污染物浓度场、通风效率及人体热舒适性等方面均优于混合通风的几种气流组织形式.

| Abstract: | Based on the computational fluid dynamics and numerical heat transfer theory,the physical and mathematical models of four typical ventilation forms are set up with Fluent software.The indoor air distribution is simulated with equation turbulence model and simple method.The velocity fields,temperature fields and concentration fields of the four air distributions in office are analyzed.When the inlet velocity of air is relatively low,the performance of transpositional ventilation in temperature field,contaminant concentration field and thermal comfort is better than the mixed ventilation and the quantity of contaminant in supply air has large influence on their indoor air distribution. |
