Adaptability or nonadaptability of a discrete model of fluid equations and the verification of CFD reliability 流体方程式の離散化モデルの適合性・非適合性とCFD信頼性検証 相曽, 秀昭 高橋, 匡康 Aiso, Hideaki Takahashi, Tadayasu 数値シミュレーション 離散モデル 連続モデル 流れ方程式 Euler運動方程式 衝撃波 電波速度 検証 信頼性 振動 numerical simulation discrete model continuous model flow equation Euler equation of motion shock wave propagation velocity validation reliability vibration The reliability of numerical simulation technology is concerned. Numerical simulation consists of several procedures between the phenomenon that is analyzed and the result that is understood by people. In some sense there are several convert of problems between two different categories, i.e. the problem is converted from phenomenon in physics to numerical model that is usually continuous model, then to discrete model, to program, to numerical result, and finally to the result like visualized picture by which people understands the phenomenon. Mathematical analysis should be very useful to analyze the relation between the continuous and discrete model, while the problem still includes some difficulties. Here, this problem is understood from the concept of consistency and it is discussed which direction the research should progress to. 資料番号: AA0045948014 レポート番号: NAL SP-57 conference paper 航空宇宙技術研究所 National Aerospace Laboratory (NAL) 2003-03 application/pdf 航空宇宙技術研究所特別資料: 航空宇宙数値シミュレーション技術シンポジウム2002論文集 57 75 80 Special Publication of National Aerospace Laboratory: Proceedings of Aerospace Numerical Simulation Symposium 2002 0289-260X AN10097345 https://jaxa.repo.nii.ac.jp/record/38235/files/nalsp0057014.pdf https://jaxa.repo.nii.ac.jp/records/38235 jpn
