Methods Pressure intensity, air cleanliness, and air velocities of the lab were measured by the manometer, photoelectric particle counter, and thermo-electric anemometer respectively, all of them had been examined by the authorized qualitative units. 空气洁净度、压强、空气流速分别采用了光电粒子计数器、微压计、热电风速仪测量。仪器均经计量单位年检。
Air velocities, velocity pressure head and total pressure head were measured by electrical anemometer, Pitot tube and the inclined manometer respectively. 风速、动压、全压分别采用了热电风速仪、皮脱管和倾斜式微压计测量。
Based on the traditional flow field validation, which is the combination of pressure measuring method using parallel pitot tube plus pressure scanner system and velocity measurement method using hot wire anemometer, the velocity uniformity and wind attack angle are checked using PIV method. 在传统的流场测试手段&多孔探针结合压力扫描阀的测压方法和热线风速仪等的流场校测的基础上,采用PIV方法对风速均匀性和风攻角等进行了校测。
