Transition of the surface boundary layer seems to start at around Re = 3 x 10(exp 5), where the Strouhal number jumps up from 0.2 to 0.45, while the level of the Aeolian tone rapidly decreases. In the transition zone, the spanwise distribution of the surface pressure fluctuation and the coherence between the Aeolian tone and the surface pressure fluctuation show strong three-dimensionality. This result shows that the decrease of the Aeolian tone in transition zone is caused by the decrease of the surface pressure fluctuation and the breakdown of the two-dimensional large scale vortex shedding.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
