One of the problems in the design method of wind-forced ventilation is that the influence of turbulent wind on ventilation is not taken into account. For example, the ventilation rate of a room with a single opening subjected to turbulent wind cannot be predicted. This paper states the need to establish a design method to allow for wind turbulence and presents its conceptual flow chart. The airflow rates through a single opening of a model enclosure subjected to artificial wind are measured by tracer-gas method, stirring the air inside the enclosure to investigate the effect of various factors (mean air velocity, turbulent intensity, opening area, incident angle of wind) upon the airflow rate. In addition, the possibility of estimating the airflow rate by means of a simple theoretical model of pulsation is examined.
