This is because the generation of turbulent vortices is suppressed by the formation of rod-like micelles, and the flow remains laminar in the high Reynolds number range. However, the values of the heat transfer coefficients decrease during flow laminarization. The research objective is to examine heat transfer enhancement effects by air injection. This paper presents an experimental investigation on the heat transfer and flow characteristics in an air-surfactant solution two-phase flow through a vertical tube. The air was injected through the porous metal. In this condition, the flow pattern of two-phase flow was bubbly flow which contains many fine bubbles in any flow rate. The bubble diameter was changed by using different types of porous metal. In every condition of air injection, heat transfer coefficients were enhanced drastically with air injection. However, the effects depend on the diameter of bubbles. The heat transfer coefficients was Increased as the diameter of bubbles decreases. This result means that the bulk concentration of rod-like micelles in a surfactant solution in bubbly flow was reduced because micelle was concentrated on the surface of bubbles.","subitem_description_type":"Abstract"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学工業高等専門学校"}]},"item_2_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"18824374","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ARAGA, Koichi"},{"subitem_text_language":"en","subitem_text_value":"NAKAMIZO, Yosuke"},{"subitem_text_language":"en","subitem_text_value":"MURATA, Keiji"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学工業高等専門学校 総合システム工学科 機械システムコース"},{"subitem_text_value":"近畿大学工業高等専門学校 専攻科 生産システム工学専攻 機械工学系"},{"subitem_text_value":"近畿大学工業高等専門学校 総合システム工学科 機械システムコース"}]},"item_2_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kinki University Technical College"},{"subitem_text_value":"Kinki University Technical College"},{"subitem_text_value":"Kinki University Technical College"}]},"item_2_version_type_12":{"attribute_name":"版","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":"荒賀, 浩一"},{"creatorName":"アラガ, コウイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中溝, 陽介"},{"creatorName":"ナカミゾ, ヨウスケ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"村田, 圭治"},{"creatorName":"ムラタ, ケイジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-19"}],"displaytype":"detail","filename":"AA12315376-20120315-0001.pdf","filesize":[{"value":"850.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA12315376-20120315-0001.pdf","url":"https://kindai.repo.nii.ac.jp/record/12812/files/AA12315376-20120315-0001.pdf"},"version_id":"3bc90c0e-13d9-43a0-9980-6c90aea4e921"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Drag Reduction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Surfactant Solution flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Heat transfer enhancement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Two phase flow","subitem_subject_language":"en","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"垂直上昇界面活性剤水溶液流れに及ぼす気泡混入の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"垂直上昇界面活性剤水溶液流れに及ぼす気泡混入の影響"},{"subitem_title":"Effect of Air Injection on Drag Reducing Surfactant Solution Vertical Flow","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["2411","3735"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-06"},"publish_date":"2012-07-06","publish_status":"0","recid":"12812","relation_version_is_last":true,"title":["垂直上昇界面活性剤水溶液流れに及ぼす気泡混入の影響"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T18:42:55.700826+00:00"}
