Moreover, at a narrow tip clearance, the pump head became partially higher in two-phase flow than that in single-phase flow. However, the internal pressure fluctuations on this pump due to air entrainment have not been studied yet. For that reason, we have examined the influences of void fraction, flow coefficient and impeller tip clearance on pressure fluctuations in the casing. At narrow tip clearance, the pump head increment in two-phase flow mainly depends on the pressure increasing in the volute casing. And the void fraction became larger, the influence of tip clearance on pressure distribution became less. Moreover, we have observed the internal flow patterns by using a stroboscope and a halogen sheet light. Then, we have investigated the influences of flow coefficient on air-water two-phase pump performance.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_21_publisher_7":{"attribute_name":"出版社","attribute_value_mlt":[{"subitem_publisher":"日本機械学会","subitem_publisher_language":"ja"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1299/kikaib.66.1126","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"著作権関連情報","attribute_value_mlt":[{"subitem_rights":"社団法人日本機械学会. 本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_21_select_59":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_21_source_id_10":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00187441","subitem_source_identifier_type":"NCID"}]},"item_21_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1884-8346","subitem_source_identifier_type":"EISSN"},{"subitem_source_identifier":"0387-5016","subitem_source_identifier_type":"PISSN"}]},"item_21_version_type_58":{"attribute_name":"出版タイプ","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":"金, 由澤","creatorNameLang":"ja"},{"creatorName":"Kim, You-Taek","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"503","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Tanaka, Kazuhiro","creatorNameLang":"en"},{"creatorName":"田中, 和博","creatorNameLang":"ja"},{"creatorName":"タナカ, カズヒロ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Tanaka","familyNameLang":"en"},{"familyName":"田中","familyNameLang":"ja"},{"familyName":"タナカ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kazuhiro","givenNameLang":"en"},{"givenName":"和博","givenNameLang":"ja"},{"givenName":"カズヒロ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"471","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"80171742","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000080171742"},{"nameIdentifier":"55624483319","nameIdentifierScheme":"Scopus著者ID","nameIdentifierURI":"https://www.scopus.com/authid/detail.uri?authorId=55624483319"}]},{"creatorNames":[{"creatorName":"山田, 五代治","creatorNameLang":"ja"},{"creatorName":"Yamada, Iyoji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"505","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"松本, 洋一郎","creatorNameLang":"ja"},{"creatorName":"Matsumoto, Yoichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"506","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":"2007-11-19"}],"displaytype":"detail","filename":"0387-5016_66-644-p1126.pdf","filesize":[{"value":"685.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"0387-5016_66-644-p1126.pdf","url":"https://kyutech.repo.nii.ac.jp/record/107/files/0387-5016_66-644-p1126.pdf"},"version_id":"0f08c0c0-c8e0-4965-a490-c8b807a14f9c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Turbomachinery","subitem_subject_scheme":"Other"},{"subitem_subject":"Multi-Phase Flow","subitem_subject_scheme":"Other"},{"subitem_subject":"Screw-Type Centrifugal Pump","subitem_subject_scheme":"Other"},{"subitem_subject":"Pressure Distribution","subitem_subject_scheme":"Other"},{"subitem_subject":"Flow Visualization","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":"空気吸入によるねじ形遠心ポンプ内の圧力変動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"空気吸入によるねじ形遠心ポンプ内の圧力変動","subitem_title_language":"ja"},{"subitem_title":"Pressure Fluctuations due to Air Entrainment in a Screw-Type Centrifugal Pump","subitem_title_language":"en"}]},"item_type_id":"21","owner":"3","path":["24"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-11-19"},"publish_date":"2007-11-19","publish_status":"0","recid":"107","relation_version_is_last":true,"title":["空気吸入によるねじ形遠心ポンプ内の圧力変動"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2025-07-14T02:30:36.819239+00:00"}
