The steady Stokes equations are known to be derived by minimizing the integral of the dissipation over the whole flow domain under the constraint of the equation of continuity. Considering the uniform flow at the outer boundary and the no-slip condition on the body surface, it is shown that the minimization of the dissipation is equivalent to that of the drag force acting on the body. Consequently, the drag force in the Stokes flow is smaller than that acting in the flow governed by the Navier-Stokes equations. To check the validity of the above theory, the numerical simulation was conducted by varying the Reynolds numbers.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: 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 illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA2030013011","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-20-008","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":"東京大学"},{"subitem_text_value":"東京大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"The University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"The University of Tokyo"}]},"item_5_version_type_30":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小島, 直泰"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木, 宏二郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KOJIMA, Naoyasu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SUZUKI, Kojiro","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":"2021-02-08"}],"displaytype":"detail","filename":"AA2030013011.pdf","filesize":[{"value":"564.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA2030013011.pdf","url":"https://jaxa.repo.nii.ac.jp/record/47332/files/AA2030013011.pdf"},"version_id":"910088a3-4aa8-4553-84b1-133ee021a7ee"}]},"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":"変分原理に基づく流体中の物体に働く抗力や形状に関する統一理解にむけて","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"変分原理に基づく流体中の物体に働く抗力や形状に関する統一理解にむけて"}]},"item_type_id":"5","owner":"1","path":["1891","2106","2108","2109"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-02-08"},"publish_date":"2021-02-08","publish_status":"0","recid":"47332","relation_version_is_last":true,"title":["変分原理に基づく流体中の物体に働く抗力や形状に関する統一理解にむけて"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:41:08.246444+00:00"}
