This analysis method was used to analyze one-dimensional phenomena such as surge phenomenon in the past. For example, POGO, which is an auto-oscillation where the thrust oscillation of rocket propulsion system including turbopumps is coupled with the natural frequency of the rocket structure, has been analyzed using this method. In the present study, cavitation compliance and mass-flow gain factor were divided and distributed in each flow path of an inducer and tried to evaluate the possibility of analyzing rotating phenomena such as rotating cavitation by this one-dimensional analysis method. Whirl motion of the rotor assembly was accounted for by variable flow area orifices which connect the next flow path. The areas of the orifices are changed harmonically and the oscillation phase of each orifice is given according to the number of the blades. The variation of leakage flow rate through the tip clearances of each blade is simulated by the motion of the variable flow area orifices. With the evolved analysis model, effects of various parameters on the eigenvalues of the system were investigated. Analysis results showed that there existed rotating phenomena and agreed with inducer test results qualitatively.","subitem_description_type":"Other"}]},"item_7_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_7_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1610062000","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Japan Society of Mechanical Engineers"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.1299/transjsme.15-00125"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1299/transjsme.15-00125","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2187-9761","subitem_source_identifier_type":"ISSN"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"志村, 隆"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川崎, 聡"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"内海, 政春"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shimura, Takashi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawasaki, Satoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uchiumi, Masaharu","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Rotating cavitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Inducer","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pump dynamic characteristics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"One-dimensional system analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Multidomain","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":"旋回キャビテーションの一次元マルチドメイン解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"旋回キャビテーションの一次元マルチドメイン解析"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-06-20"},"publish_date":"2016-06-20","publish_status":"0","recid":"22681","relation_version_is_last":true,"title":["旋回キャビテーションの一次元マルチドメイン解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:17:09.103360+00:00"}
