높은 받음각 영역에서 plunge 운동을 하는 강체 평판의 공력 성능

다국어 초록 (Multilingual Abstract)

In this paper, the aerodynamic performance of a rigid plunging plate at high angles of attack is presented. The forces acting on the plate at a post-stall angle of attack of 15 degrees with the amplitude of 15% of the chord are computed, and compared with the experimental results. For the numerical simulation, a three-dimensional preconditioned Navier-Stokes solver is adopted. When compared to the experimental results, the present method capture not only the trend of the averaged force coefficients but also the characteristics of the flow fields.
