| 抄録: | Recently, a turbulent boundary layer is generally used to investigate wind effects of tallbuildings. In this case, it is thought that the flow in the wind tunnel is usually devided into themean and fluctuating components, and each statistic has a unique value if an averaging time is de-termined. However, in practice, each statistic is changed in according to the length of this aver-aging time, and it is not uniquely determined. This is caused by the fluctuating components witha longer period than averaging time in the flow wind tunnel. So the experiments were conductedin some wind tunnels investgating the low frequency fluctuations which affect the decision of theaveraging time. We found that there are low frequency components with longer scales than thelength of wind tunnel. |
