Abstract

航空宇宙技術研究所 7-9 Jun. 1995 東京 日本, National Aerospace Laboratory 7-9 Jun. 1995 Tokyo Japan, パイプやチャネルのような単純形状をもつ乱流の数値解析が、数多くのLES(大型渦シミュレーション)やDNS(直接数値シミュレーション)を用いて行われている。ここでは、LESやDNSのデータベースからのデータを基に生成、散逸、拡散の数値解析を再構成し、コンピュータグラフィックスを用いて可視化した。流路内壁面近傍の乱流の動画化を行い、乱流の複雑な流力現象の理解を深めるようにした。, A large number of LES (Large Eddy Simulation) and DNS (Direct Numerical Simulation) have been made for turbulent flows with simple geometries such as a pipe and a channel. In the present study, production, dissipation and diffusion terms are obtained from the LES and DNS data bases and visualized with the use of computer graphics. The animation of the near-wall turbulence structure enables further understandings of the complex turbulence phenomena., 資料番号: AA0000294028, レポート番号: NAL SP-30
