It is observed that four vortex axes, each of which has the vorticity of opposite directions with its neighboring two vortex axes, approach each other due to an effect of their curvatures., 資料番号: AA0001960023, レポート番号: NAL SP-43}, pages = {79--80}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {一様等方乱流中の渦軸の相対運動}, volume = {43}, year = {1999} }
