Mielparque-tokyo), Minato-ku, Tokyo, Japan, In this study, the spatial correlation structure of fluctuating surface pressure acting on a fixed circular cylinder was investigated by wind tunnel tests and the computational fluid dynamics (CFD). Our study involved an examination of the following two effects: 1.) the aspect ratio of the model and 2.) the boundary conditions of the sidewalls for CFD on the fluctuating surface pressure acting on a fixed circular. This study produced the finding that the special correlation of the fluctuating pressure on a fixed circular cylinder was affected by the aspect ratio of the model. A proper orthogonal decomposition (POD) analysis indicated that the fluctuating surface pressure acting on a circular cylinder had symmetric and asymmetric mode shapes along the axis of the cylinder, and these modes affected the spatial correlation of the fluctuating aerodynamic forces acting on the cylinder., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1630046038, レポート番号: JAXA-SP-16-008E}, pages = {367--374}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {Study on spatial correlation structure of fluctuating pressure acting on a circular cylinder}, volume = {JAXA-SP-16-008E}, year = {2017} }
