The Reynolds number is set to be 1020 based on the friction velocity and the channel half width. It is shown that large-scale structures of the streamwise velocity fluctuations appear hierarchically in the intermediate and outer regions. Indeed, the large-scale structures in the intermediate region appear noticeably at the present Reynolds number, which can hardly be recognized at low Reynolds numbers., 資料番号: AA0049212020, レポート番号: JAXA-SP-05-017}, pages = {124--125}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Re(sub tau)=1020の平行平板間乱流のDNSに見る階層的な乱流構造}, volume = {JAXA-SP-05-017}, year = {2006} }
