The Reynolds number is set to be 180, 395 and 640 based on the friction velocity and the channel half-width. The molecular Prandtl number is 0.71. Near the wall, the scalar dissipation field is associated primarily with anisotropic structures, which reflect the presence of quasi-streamwise vortices, whereas away from the wall, it is mainly sheet-like in form., 資料番号: AA0063154025, レポート番号: JAXA-SP-06-010}, pages = {137--138}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {平行平板間乱流熱伝達のDNSによるスカラー散逸場の構造解析}, volume = {JAXA-SP-06-010}, year = {2006} }
