The formation process of the 'Fingers' induced artificially by a fine wire set to perturb the flow is clarified in the wake of a circular cylinder. At the location where the 'Fingers' are formed, the shedding frequency of the vortices in the near wake of the cylinder is slightly lower than the shedding frequency at the same location without 'Fingers'. This local discrepancy of the shedding frequency creates the time variation of the phase difference of the vortex shedding in the spanwise direction. When the phase difference increases to some extent, a vortex filament reconnects the other vortex filament and the phase difference diminishes temporarily. The origin of 'Fingers' exists in the reconnection of vortex filaments.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
