The power spectrum of velocity fluctuations shows the presence of quasi-periodic motion in the model flow. It is argued that a possible mechanism responsible to the occurrence of the quasi-periodicity might be the inviscid, varicose-mode instability of a symmetric flow which consists of a boundary layer flow and its mirror image with respect to the wall., 資料番号: AA0045947012, レポート番号: NAL SP-56}, pages = {41--44}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {乱流境界層外層域の擬周期性について}, volume = {56}, year = {2002} }
