Tangent-Ogive-Cylinder 비행체의 고앙각에서의 비대칭 와류 특성 연구

A COMPUTATIONAL STUDY ON THE CHARACTERISTICS OF ASYMMETRIC VORTEX OF TANGENT-OGIVE-CYLINDER FLIGHT VEHICLE AT HIGH ANGLES OF ATTACK

The characteristics of asymmetric vortex and side force of tangent-ogive-cylinder flight vehicle at high angles of attack have been performed by using upwind Navier-Stokes method with the ${\kappa}-{\omega}$ turbulence model. And Asymmetric transition positions are considered for generation of asymmetric vortex.
