Stability analysis is also made for the wake velocity distributions to obtain their local instability characteristics. In the initial stage, the frequency of growing disturbance agrees well with that of absolutely unstable disturbance for the (initial) steady wake, but it increases as the wake shera-layers roll up to the vortex streets. Such increase of the frequency is also explained by the alteration n of the absolute instability characteristics of the near-wake.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
