The theory was reviewed within the framework of functional analysis and updated with another expression of the shape derivative with respect to the objective function. A computer program was developed with the FreeFEM++. Numerical analyses were performed for two types of problems: a two-dimensional Poiseuille flow field with a sudden expansion and a two-dimensional uniform flow field around an isolated body. From the first example, two local minimum points of symmetric and asymmetric flow fields were determined, and the asymmetric flow field was found to be more stable. With regard to the second example, we reached the local minimum point of an elliptical shape, and infrequently determined a solution converging to an elliptical shape with the bluff in the leeward direction. By comparison, the superiority of the elliptical shape was obvious.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"ファイル公開：2019/08/01","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Taylor & Francis","subitem_publisher_language":"en"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1080/10618562.2018.1500692","subitem_relation_type_select":"DOI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"This is an Accepted Manuscript of an article published by Taylor & Francis Group in International Journal of Computational Fluid Dynamics on 01/08/2018, available online: http://www.tandfonline.com/10.1080/10618562.2018.","subitem_rights_language":"en"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_10_source_id_61":{"attribute_name":"ISSN（print）","attribute_value_mlt":[{"subitem_source_identifier":"1061-8562","subitem_source_identifier_type":"PISSN"}]},"item_10_source_id_62":{"attribute_name":"ISSN（Online）","attribute_value_mlt":[{"subitem_source_identifier":"1029-0257","subitem_source_identifier_type":"EISSN"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kiriyama, Yasuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"88619","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katamine, Eiji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"88620","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Azegami, Hideyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"88621","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":"2019-08-01"}],"displaytype":"detail","filename":"main.pdf","filesize":[{"value":"2.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"main","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/27052/files/main.pdf"},"version_id":"e03ac24b-423c-4181-9df7-dd958ee76810"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Navier–Stokes flow","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrodynamic stability","subitem_subject_scheme":"Other"},{"subitem_subject":"linear disturbance","subitem_subject_scheme":"Other"},{"subitem_subject":"shape optimisation","subitem_subject_scheme":"Other"},{"subitem_subject":"finite element method","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Shape optimisation problem for stability of Navier–Stokes flow field","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Shape optimisation problem for stability of Navier–Stokes flow field","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["314"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-02-06"},"publish_date":"2019-02-06","publish_status":"0","recid":"27052","relation_version_is_last":true,"title":["Shape optimisation problem for stability of Navier–Stokes flow field"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:17:49.535071+00:00"}
