The results show that the pressure loss tendencies against the bearing revolution speed were significantly different between the flow directions. It was mainly caused by the flow separation behind the ball and centrifugal force effect of swirl flow made by bearing revolution. Furthermore, we get a simplified pressure loss model of the bearing and it can approximately estimate the difference of the pressure losses between the flow directions.","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1510106000","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本工業出版"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.11458/tsj.39.358"}],"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.11458/tsj.39.358","subitem_relation_type_select":"DOI"}}]},"item_7_rights_28":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©2011 日本工業出版"}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-8839","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00004836","subitem_source_identifier_type":"NCID"}]},"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)"},{"subitem_text_value":"(株)IHI"}]},"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)"},{"subitem_text_language":"en","subitem_text_value":"IHI Corporation"}]},"item_7_version_type_30":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"川崎, 聡"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"木村, 俊哉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"内海, 政春"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"須田, 一志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawasaki, Satoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kimura, Toshiya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Uchiumi, Masaharu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Suda, Kazushi","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":"2020-01-22"}],"displaytype":"detail","filename":"PA1510106000.pdf","filesize":[{"value":"838.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PA1510106000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/22589/files/PA1510106000.pdf"},"version_id":"4f9cc73c-a7b3-4574-b149-ae9f9c9d33c2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Bearing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Numerical Analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pressure Loss","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Rocket Turbopump","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":"ロケット用ターボポンプ玉軸受の冷却流れ圧力損失に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ロケット用ターボポンプ玉軸受の冷却流れ圧力損失に関する研究"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-11-27"},"publish_date":"2015-11-27","publish_status":"0","recid":"22589","relation_version_is_last":true,"title":["ロケット用ターボポンプ玉軸受の冷却流れ圧力損失に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:18:34.982541+00:00"}
