Effects of perturbations with an infinitely small amplitude on a fundamental steady flow in the channel were numerically investigated. The fundamental flow corresponds to one of the steady solutions of the Navier-Stokes equations. Time-asymptotic solutions of the perturbation equations reach the least stable mode of the channel flow. Growth or decay of the perturbations was supposed to occur everywhere in the flow with a constant amplification factor, since the logarithmic value of the maximum transverse perturbation velocity of the least stable mode changed linearly with time at all monitoring locations in the channel. In addition, a direct numerical calculation was performed using the two-dimensional Navier-Stokes equations to investigate the characteristics of nonlinear stability, the results of which showed a similar growth pattern to those derived from the perturbation equations. The flow instability with an increase of the Reynolds number was found to depend on the value of the source functioning term of the perturbation vorticity equation derived from the perturbation equations.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "44941", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Matsubara, Koji"}]}, {"nameIdentifiers": [{"nameIdentifier": "44942", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Nakabe, Kazuyoshi"}]}, {"nameIdentifiers": [{"nameIdentifier": "44943", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Suzuki, Kenjiro"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本機械学会"}]}, "item_5_relation_31": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110002395001", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "日本機械学会"}, {"subitem_rights": "本文データは学会の許諾に基づくCiNiiからの複製である"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00187441", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03875016", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "松原, 幸治"}], "nameIdentifiers": [{"nameIdentifier": "44938", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中部, 主敬"}], "nameIdentifiers": [{"nameIdentifier": "44939", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "鈴木, 健二郎"}], "nameIdentifiers": [{"nameIdentifier": "44940", "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": "2019-07-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "9_0048.pdf", "filesize": [{"value": "600.7 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 600700.0, "url": {"label": "9_0048.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3722/files/9_0048.pdf"}, "version_id": "c2951eb8-5291-4721-adc0-6b793a475994"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Unsteady Flow", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Forced Convection", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Transition", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Numerical Analysis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Linear Stability", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Low Reynolds Number", "subitem_subject_scheme": "Other"}]}, "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "リブ付き平行平板間流れの線形安定性解析", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "リブ付き平行平板間流れの線形安定性解析"}, {"subitem_title": "リブ付き平行平板間流れの線形安定性解析", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/5750", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-04-08"}, "publish_date": "2008-04-08", "publish_status": "0", "recid": "3722", "relation": {}, "relation_version_is_last": true, "title": ["リブ付き平行平板間流れの線形安定性解析"], "weko_shared_id": null}
