摘要对一个足尺模型建筑在横向通风条件下的墙体和楼板风压进行了观测。还进行了空气流量的测量，并评估了现有的空气流量预测理论，即孔板流量方程，包括流量系数，其准确性。同时，提出了一种预测流量系数的方法，并进行了试验。最后，提出了流量系数与孔口风压系数差之间的关系式。此外，还介绍了孔板流量方程应用困难的背景。
Abstract The observation of wind pressure acting on the wall and floor of a full-scale building model under cross ventilation was carried out. The measurement of air flow was also undertaken, and the existing prediction theory of the air flow rate, namely the orifice flow equation, including the discharge coefficient, was evaluated for its accuracy. At the same time, a method of predicting the discharge coefficient has been proposed and tested. In conclusion, a tentative relationship between the discharge coefficient and the difference of wind pressure coefficient across the opening has been developed. In addition, the background concerning the difficulty of using the orifice flow equation has been described.
