摘要 大开口自然通风的流动机理与渗风模型有较大不同,通过对大开口自然通风伯努利方程的分析,探讨了空气流动的局部阻力机理,指出在大开口自然通风的流动过程中流量系数的物理含义及其应注意的问题。 The flow mechanisms of natural ventilation through large opening are different from that of infiltration model. By the analysis of Bernoulli equation applied in natural ventilation through large opening, discusses the local resistance properties of the air flow, and proposes the physical meaning of discharge coefficient through large opening and some problems needed attentions.
