Flow variables on a large number of grid points are hardly defined by spatiotemporally limited amount of measurement data that poses an underdetermined problem. In this study we conduct sensitivity analysis of a vortex flow field by the use of an adjoint method. The idea of optimal/targeted observation in meteorology which aim to effectively determine a flow state by limited observations is interpreted in fluid dynamic problems where unsteady flows of much smaller scales are of interest.","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: AA0062070015","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-13-001E","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_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東北大学流体科学研究所"},{"subitem_text_value":"東北大学流体科学研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Fluid Science, Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Institute of Fluid Science, Tohoku University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三坂, 孝志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大林, 茂"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Misaka, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Obayashi, Shigeru","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":"2020-01-16"}],"displaytype":"detail","filename":"62070015.pdf","filesize":[{"value":"217.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"62070015.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4123/files/62070015.pdf"},"version_id":"46f71528-434c-436a-9fad-a6654bc8b574"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"sensitivity analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"4D-Var","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"large-eddy simulation","subitem_subject_language":"en","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Sensitivity Analysis of Unsteady Flow Fields and Numerical Experiments for Optimal Measurement","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Sensitivity Analysis of Unsteady Flow Fields and Numerical Experiments for Optimal Measurement","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["887","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"4123","relation_version_is_last":true,"title":["Sensitivity Analysis of Unsteady Flow Fields and Numerical Experiments for Optimal Measurement"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:47:05.720938+00:00"}
