5공 피토관을 이용한 3차원 유동장 측정(1)

Abstract

직접 설계 제작한 5공 피토관을 이용하여 3차원 유동장을 측정하기 위해서는 이 피토관의 특성을 나타내는 특성 곡선인 검정식이 필요하다. 이러한 검정식을 무차원 매개변수를 도입하여 제시하였고 정확한 위치제어를 위해 자동이송장치를 개발하였다.

We directly designed and produced five hole pitotube to measure three dimensional flow field. To measure the flow field by the pitot tube, we need it's calibration equation which denotes it's characteristics. From the result of this study the calibration equation was suggested by using dimensionless parameters and an automatic traverse system was developed to control the measuring position precisely.
