엇회전식 축류팬의 복잡한 유동특성을 이해하고 설계, 공력 해석 및 소음 특성 예측에 활용될 수 있는 3차원 비정상 유동장을 측정하였다. 엇회전식 축류팬의 3차원 비정상 유동장은 작동 영역인 설계점에서
For the understanding of the complex flow characteristics in the counter-rotating axial flow fan, it is necessary to investigate the three-dimensional unsteady flow fields in the counter-rotating axial flow fan. This information is also essential for the prediction of the aerodynamic and acoustical characteristics of the counter-rotating axial flow fan. Experimental study on the three-dimensional unsteady flow in the counter-rotating axial flow fan is carried out at the design point(operating condition). Three-dimensional unsteady flow fields in the counter rotating axial flow fan are measured at the cross-sectional planes of the upstream and downstream of each rotor using the
