摘要
The simple surface wind sensor proposed by Irwin measures wind speeds through pressure differences. It has been applied in several wind-tunnel laboratories for the study of pedestrian-level wind conditions. However, some characteristics related to sensor performance for wind-tunnel measurements have not been fully investigated. Discussed in this paper are: calibration of the sensor for measuring mean and rms wind speeds, the effect of sensor height on measurement errors, the interference between nearby sensors, and the response of sensors to turbulent wind conditions. Data presented here supplement Irwin's original results on the surface wind sensor and provide additional insight in the performance of the sensor.
