기울어진 정방형 실린더에 작용하는 유체력

초록

Numerical investigation has been carried out for laminar flow (Re≤150) past a square cylinder in cross freestream with an angle of attack. This study would be the first step towards understanding flow-induced forces on cylindrical structures under a strong gust of wind from the viewpoint of wind hazards. Collecting all the numerical results obtained, we propose contour diagrams of drag/lift coefficients and Strouhal number (St) on an Re–Angle plane.
