The fully-developed turbulent flow and the passive scalar field are obtained through the DNS with 512(exp 3) mesh points. The numerical analysis and visualization of the flow reveal that the intense portions of the turbulent vorticity concentrate in the sheet-like regions at the early stage. Then, the sheets roll up and finally form vortex tubes that are called worm. The tubes are also observed in the lower-vorticity regions. Furthermore, the intense portions of temperature gradient concentrate in the sheet-like regions and remain unchanged contrary to those of the vorticity.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
