The method suppresses time periodic flows driven only by the non-stationary boundary condition at a sufficiently low Reynolds number using Snapshot Proper Orthogonal Decomposition (Snapshot POD). For shape optimization, the eigenvalue in Snapshot POD is defined as a cost function. The main problems are Reynolds Average Navier-Stokes problems and eigenvalue problems of Snapshot POD. An objective functional is described using Lagrange multipliers and finite element method. Two-dimensional cavity flow with a disk-shaped isolated body is adopted. The nonstationary boundary condition is defined on the top boundary and non-slip boundary condition for side and bottom boundaries and for the disk boundary. For numerical demonstration, the disk boundary is used as the design boundary. Using H1 gradient method for domain deformation, all triangles over a mesh are deformed as the cost function decreases, where the sensitivities in the boundary integration type and the volume integration type are adopted to comparison both. To avoid decreasing the numerical accuracy based on squeezing triangles, AMR is applied throughout the shape optimization process to maintain equal numerical accuracy to that of a mesh in the initial domain.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1830029013","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-18-005","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"大阪大学数理・データ科学教育研究センター"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Center for Mathematical Modeling and Data Science, Osaka University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中澤, 嵩"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakazawa, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"AA1830029013.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830029013.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2942/files/AA1830029013.pdf"},"version_id":"ebdb30ca-5cbe-40fe-b509-f53f4ecb9368"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"数理・データ科学の融合による流体制御","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"数理・データ科学の融合による流体制御"}]},"item_type_id":"5","owner":"1","path":["1531","1875","1891","1976"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-02-28"},"publish_date":"2019-02-28","publish_status":"0","recid":"2942","relation_version_is_last":true,"title":["数理・データ科学の融合による流体制御"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:13:26.407806+00:00"}
