In this method thermal nodal points are assigned to several representative points of the spacecraft and the thermal balance equations for each nodal point are simultaneously solved. The thermal conductance between the nodal points is corrected using the physical simulation data and the flight data. This may serve as an example in which numerical analysis of the total system can completely replace the physical simulation using large space simulation chambers. Secondly, a vortex method in computational fluid dynamics, re-classified as a mathematical model, is described. In this method the conservation equation of vorticity fixed to the fluid mass elements serves as the basic equation. It has no direct connection with Navier-Stokes equations. The creation of the vorticity is phenomenologically modelled, and the decay is taken into account through numerical dissipation and/or decay of the viscous core. The usefulness of this concept is demonstrated by the unsteady flow field around a rotating elliptic cylinder simulated by this method, which could predict the existence of wake oscillation unrelated to the body oscillation. This existence was confirmed experi-mentally later. Thirdly, the self-similarity of flow fields is discussed, and the concepts of the first and second kinds of self-similarity and of the intermediate asymptotes are introduced. All numerical analysists of fluid dynamic problems should be very careful of the dynamical similarity of the problem which may be involved. Finally, some words are given on the international Conference on Numerical Methods in Fluid Dynamics, which has been playing an internationally important role in information exchange of computational fluid dynamics.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0001001","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL SP-1","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙科学研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大島, 耕一"}],"nameIdentifiers":[{"nameIdentifier":"462310","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Oshima, Koichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"462311","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-28"}],"displaytype":"detail","filename":"nalsp0001001.pdf","filesize":[{"value":"583.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0001001.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43119/files/nalsp0001001.pdf"},"version_id":"4575a50a-d872-4b0e-b4fb-33f0edff53de"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"世界の数値流体力学研究の動向","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"世界の数値流体力学研究の動向"}]},"item_type_id":"3","owner":"1","path":["1893","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"43119","relation_version_is_last":true,"title":["世界の数値流体力学研究の動向"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:22:29.397302+00:00"}
