In the case of a flat plate perpendicular to the uniform flow, the wavy deformation of the vortex filament was observed in the far wake. In the case of an inclined plate, the rib structures appeared in regular intervals to the axial direction in a vortex filament at the near wake. The ribs generate around a pair of vortex filaments which are shedding alternately from a plate. The absolute value of circulation of alternate vortex was different from each other in a pair of vortices in the case of an inclined plate. It seems that three dimensional deformation of vortex in the near wake is caused by difference of circulation of alternate vortex. The similar phenomenon was observed in the wake behind a circular cylinder oscillating in the streamwise direction., 形態: カラー図版あり, 資料番号: AA0064237011, レポート番号: JAXA-SP-08-006}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {二次元物体伴流渦の変形モードについて}, volume = {JAXA-SP-08-006}, year = {2009} }
