The latter waves may have the common or similar characteristics to the horseshoe-shaped vortices arising from a viscous (laminar) sublayer in a turbulent boundary layer. In the present work, we investigated the evolution of the two-dimensional waves, the dynamics of the horseshoe-shaped waves and the associated gas absorption. At large wave frequencies, nearly sinusoidal waves appear on the film and are decelerating as they are growing. At small frequencies, tear-drop-shaped solitary waves occur and show acceleration. Then they gradually increase the transverse disturbances and change into the horseshoe-shaped waves. At intermediate frequencies, transition from single-peaked waves to double-peaked waves and vice versa are observed. When putting transverse disturbances of constant wavelength, \u03bb_h on the two-dimensional solitary waves, the waves are stable to the disturbances of \u03bb_h = 30 mm or less at small Reynolds numbers Re. The waves are unstable to the disturbances at intermediate and large Reynolds numbers, and develop into the horseshoe-shaped waves. The waves are more unstable to the transverse disturbances of shorter wavelength, and the growth rate of the disturbance increases with Re. The transition of gas absorption of a falling film occurs at Re - 40, and the present experimental results show that the transition of gas absorption is caused by the transition from two-dimensional waves to horseshoe-shaped waves.", "subitem_description_type": "Other"}, {"subitem_description": "\u7814\u7a76\u5831\u544a\u66f8", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u91ce\u5e95\u6b66\u6d69"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/10927"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "NCID", "subitem_1522646572813": "BA64352260"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "research report", "resourceuri": "http://purl.org/coar/resource_type/c_18ws"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "11650231-5.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2004697/files/11650231-5.pdf"}, "version_id": "44906226-c8eb-480d-af57-2300219a15a0"}, {"accessrole": "open_access", "download_preview_message": "", "file_order": 1, "filename": "11650231-4.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2004697/files/11650231-4.pdf"}, "version_id": "39afeac9-8823-4a14-8b34-a8ba2fc31b73"}, {"accessrole": "open_access", "download_preview_message": "", "file_order": 2, "filename": "11650231-3.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2004697/files/11650231-3.pdf"}, "version_id": "6aa2e8de-7f01-48f6-b41d-f37c0020603b"}, {"accessrole": "open_access", "download_preview_message": "", "file_order": 3, "filename": "11650231-2.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2004697/files/11650231-2.pdf"}, "version_id": "ed47588c-c367-4315-bfaf-792da6472874"}, {"accessrole": "open_access", "download_preview_message": "", "file_order": 4, "filename": "11650231-1.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2004697/files/11650231-1.pdf"}, "version_id": "d2554b73-f2d2-42cc-b915-988df1488523"}]}, "item_title": "\u6d41\u4e0b\u6db2\u819c\u306b\u751f\u305a\u308b\u99ac\u8e44\u5f62\u8868\u9762\u6ce2\uff08\u6e26\uff09\u306e\u904b\u52d5\u7279\u6027", "item_type_id": "15", "owner": "1", "path": ["1642838403123", "1642838406845"], "permalink_uri": "http://hdl.handle.net/20.500.12000/10927", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-06-15"}, "publish_date": "2009-06-15", "publish_status": "0", "recid": "2004697", "relation": {}, "relation_version_is_last": true, "title": ["\u6d41\u4e0b\u6db2\u819c\u306b\u751f\u305a\u308b\u99ac\u8e44\u5f62\u8868\u9762\u6ce2\uff08\u6e26\uff09\u306e\u904b\u52d5\u7279\u6027"], "weko_shared_id": -1}
