Abstract
This paper deals with experimental study of active flow control via synthetic jet for separated flow. First, we designed jet exit configuration to improve flow control performance by adjusting some key parameters, such as a hole diameter and hole gap. Second, the designed actuator was applied to an airfoil to find optimal operating frequencies and conditions for increasing the lift/drag ratio. finally, the synthetic jet was applied to the blended wing body configuration having a complex flow structure to investigate forces and moments acting on the wing. As a result, we found that the synthetic jet can be effective to the separation control under various flow conditions.
본 논문은 능동유동제어 장치의 하나인 synthetic jet을 이용한 유동박리 제어를 다루고 있다. 먼저 synthetic jet의 원형출구 지름과 간격을 조절하여 유동제어에 효과적인 jet 출구형상을 찾았다. 두 번째로 설계된 구동기를 2차원 airfoil에 적용하여 양항비 향상에 효과적인 작동주파수와 작동조건에 대해 조사하였다. 마지막으로 복잡한 유동조건을 가진 blended wing body 형상의 3차원 날개에 적용하여 힘과 모멘트 변화를 분석하였다. 그 결과 synthetic jet은 다양한 유동조건에서 유동박리제어에 효과적임을 확인할 수 있었다.
