Usually we can observe that the axes of Karman vortices in the wake of a circular cylinder are not parallel to the axis of the circular cylinder, but the angle of the Karman vortices the cylinder axis is about 15 degrees for Reynolds numbers less than one thousand. Also we can observe the axial flow in the central part of every Karman vortex. The boundary layer on a rotating circular cylinder in a uniform flow is composed of the inner layer of Taylor vortices and the outer layer of Gortler vortices, and the outer layer separates from the inner layer, resulting in forming the Karman vortex street, 資料番号: AA0064237007, 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 = {一様流に垂直な円柱周りの流れの三次元性}, volume = {JAXA-SP-08-006}, year = {2009} }
