A candidate proposed here is a certain type of streamwise vortex characterized by an annular and axisymmetric distribution of vorticity. This is because it may undergo 'inflectional instability' like in low-speed mixing layers. The inviscid linear stability analysis and direct numerical simulations have been made to clarify the 'inflectional instability'. The results demonstrates its powerful potential as a means of supersonic mixing enhancement, showing the development of complex flow driven by rapidly growing and interacting discrete vortices of various scales.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
