More Information
Summary:The present invention relates to a cylindrical structure with a penetration hole to reduce a drag force. A cylinder with a penetration hole having various angles enables a peeling point to be located at a rear side in a direction in which a fluid flows compared to a cylinder without the penetration hole. Therefore, a drag force applied to the cylinder can be reduced. 본 발명은 관통홀을 구비하여 항력을 감소시키는 원통형 구조물에 관한 것으로, 다양한 각도의 관통홀이 구비된 원통은 박리점이 관통홀이 없는 원통에 비해 유체가 흐르는 방향으로 더욱 후단 측에 위치함으로써, 상기 원통이 받는 항력을 감소시키는 것을 특징으로 한다.
