The phenomena are known as the vortex breakdown. The aim of the present research is to clarify the essential properties of the phenomena, and to obtain reasonable explanation to the multiformity of the breakdown form as well. First, the elastoid-inertia oscillation of the rotating fluid in a cylindrical vessel is examined experimentally and theoretically. As the result, some characters of the inertial wave in rotating fluid are clarified. Then the vortex breakdown phenomena in a circular pipe are investigated. In consequence, it is found that breakdown of various types correspond to the values of a parameter s which defines the azimuthal mode of the inertial wave disturbance. And it is also made clear that the breakdown of stationary type and unsteady one, observed to date, have close relation to the occurrence of inertial wave disturbances with and without phase velocity, respectively. The propriety of these conceptions is confirmed by experiments.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID\u767b\u9332", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/memfenu.37.2.117", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Faculty of Engineering, Nagoya University"}]}, "item_9_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN\uff08print\uff09", "attribute_value_mlt": [{"subitem_source_identifier": "0027-7657", "subitem_source_identifier_type": "PISSN"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Ito, Tadaya", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102086", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Suematsu, Yoshikazu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102087", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hayase, Toshiyuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102088", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2020-11-04"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "37-2-01.pdf", "filesize": [{"value": "8.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 8500000.0, "url": {"label": "37-2-01.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/30785/files/37-2-01.pdf"}, "version_id": "cefee719-5a13-45d3-b062-d46206c269cc"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "On the vortex breakdown phenomena in a swirling pipe-flow", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "On the vortex breakdown phenomena in a swirling pipe-flow", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["320/2524/2544/2557"], "permalink_uri": "https://doi.org/10.18999/memfenu.37.2.117", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-11-04"}, "publish_date": "2020-11-04", "publish_status": "0", "recid": "30785", "relation": {}, "relation_version_is_last": true, "title": ["On the vortex breakdown phenomena in a swirling pipe-flow"], "weko_shared_id": -1}
