This makes it possible to apply to a variety of two-phase flow dynamics, while the intrinsic void fraction fluctuations, typically observed in slug and churn flows, are hardly simulated. In order to break through such a problem caused by time-averaging, discrete bubble model based on one-dimensional mass conservation equation, i.e. void propagation equation, has been developed. This model takes into account, as momentum effects, the wake effect induced by preceding bubbles, the local pressure fluctuation and the compressibility of gas phase together with the phase re-distribution due to geometrical constrains. Thus obtained spatio-temporal fluctuation characteristics of void fraction well simulated inherent two-phase behavior not only in a steady flow but also in an oscillatory flow.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_9_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本伝熱学会","subitem_publisher_language":"ja"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09189963","subitem_source_identifier_type":"PISSN"}]},"item_9_version_type_17":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"網, 健行","creatorNameLang":"ja"},{"creatorName":"Ami, Takeyuki","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"梅川, 尚嗣","creatorNameLang":"ja"},{"creatorName":"Umekawa, Hisashi","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"小澤, 守","creatorNameLang":"ja"},{"creatorName":"Ozawa, Mamoru","creatorNameLang":"en"}],"familyNames":[{"familyName":"小澤","familyNameLang":"ja"},{"familyName":"Ozawa","familyNameLang":"en"}],"givenNames":[{"givenName":"守","givenNameLang":"ja"},{"givenName":"Mamoru","givenNameLang":"en"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"庄司, 正弘","creatorNameLang":"ja"},{"creatorName":"Shoji, Masahiro","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":"2019-05-22"}],"displaytype":"detail","filename":"KU-1100-20070202-02.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20070202-02.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/10654/files/KU-1100-20070202-02.pdf"},"version_id":"1a55ec54-91c3-426a-9ac1-15fbb215f7e0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Two-phase flow dynamics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Discrete bubble model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Void wave propagation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Flow pattern","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Probability density function","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Oscillatory 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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"離散気泡モデルによる二相流ダイナミクスの解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"離散気泡モデルによる二相流ダイナミクスの解明","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"1","path":["1537"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-01-28"},"publish_date":"2012-01-28","publish_status":"0","recid":"10654","relation_version_is_last":true,"title":["離散気泡モデルによる二相流ダイナミクスの解明"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-11-06T06:56:41.599345+00:00"}
