Control of Flow Over a Circular Cylinder Using a Synthetic Jet
원형 실린더에서 합성 제트를 이용한 유동 제어
Abstract
We perform an active control on flow over a circular cylinder using a synthetic jet at Re=3900. The synthetic jet is issued from a cavity located inside the cylinder, generating a train of vortices near the surface. These vortices interact with and weaken the main vortices, resulting in drag reduction at a high frequency.
