Fourier and Wavelet decompositions are applied to extract three scales, namely the large, intermediate and fine scaled structures from the flow field. Both filtering methods captured almost the same structures. An automatic tracking scheme that could handle vortex division is developed and presented., 資料番号: AA0063608004, レポート番号: JAXA-SP-07-009}, pages = {13--14}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {一様等方性乱流場における渦構造の階層性について}, volume = {JAXA-SP-07-009}, year = {2007} }
