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.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
