Zusammenfassung:The present invention relates to a wind tunnel testing device with an improved fluid rectification function. More specifically, the present invention relates to the wind tunnel testing device comprises a wind tunnel including a blower, an expansion part, a rectification part, a throttle part, and a measuring part. The rectification part includes a mesh-type rectification net, a plurality of perforated plates, and a honeycomb structure which are arranged sequentially back and forth to rectify a fluid. According to the present invention, a loss in pressure of the fluid is lowered as the flow and flow rate of the fluid in the wind tunnel rectification part becomes uniform, thereby minimizing a turbulence of the fluid in the wind tunnel measuring part. 본 발명은, 유체 정류 기능이 향상된 풍동실험장치에 관한 것으로서, 보다 상세하게는, 송풍기와, 확대부, 정류부, 교축부 및 측정부로 구성된 풍동(wind tunnel)을 포함하는 풍동실험장치로서, 정류부는, 유체를 정류시키기 위해 전후 순차적으로 배치되는 메쉬(mesh) 형태의 정류망, 복수의 타공판 및 허니컴 구조물을 포함하는 것을 특징으로 하는 유체 정류 기능이 향상된 풍동실험장치에 관한 것이다. 본 발명에 따르면, 풍동 정류부에서 유체의 흐름 및 유속이 균일화 됨으로써, 유체의 압력손실이 낮아지고, 이로 인해 풍동 측정부에서의 유체의 난류도가 최소화되는 효과가 있다.
