Study on the influence of installation angle on pitot tube in wind tunnel

Zheng Zhang, Miao Miao, Wenjia Li
Abstract:
Pitot tube is a standard instrument commonly used in wind speed measurement, which generally needs to be used in conjunction with wind tunnel. On the premise that the pitot tube coefficient is determined and the performance of other related supporting equipment (digital pressure gauge, temperature and humidity sensor) is stable, it is found that the horizontal installation angle of pitot tube in the wind tunnel will have a significant impact on the measurement of wind speed. This paper designs an experimental method for this kind of phenomenon, summarizes the experimental data, and analyzes the possible impact of this kind of phenomenon on wind speed traceability, in order to improve the accuracy and effectiveness of pitot tube wind speed measurement.
