Flow visualization tests and the cascade endwall static-pressure measurements were also made. These test results show that many vortical flows relate to the loss generation but the major process of loss generation in the cascade passage can be explained simply as a migration process in which boundary layer fluids with low energy being developed on the cascade passage walls(i.e., both endwalls and both blade surfaces) migrate onto the blade suction surface near the trailing edge. Complicated flow patterns were seen rather in the vortical flows near the trailing edge and downstream of the cascade; for example, a strong trailing-shedding-vortex occurring downstream of the cascade affects the upstream flow field within the cascade by extremely complicated mechanisms. Effects of blade tip leakage flow on the cascade internal flow and the associated loss are also shown in this paper.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0970000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-970T","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所原動機部"},{"subitem_text_value":"航空宇宙技術研究所原動機部"},{"subitem_text_value":"航空宇宙技術研究所原動機部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山本, 孝正"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"柳, 良二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"能瀬, 弘幸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMAMOTO, Atsumasa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YANAGI, Ryoji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NOUSE, Hiroyuki","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr0970t.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr0970t.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45229/files/naltr0970t.pdf"},"version_id":"9dbd291b-e377-47e5-a8b1-544ced9ac285"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Mechanisms of Secondary Flows and Losses within a Three Dimensional Turbine Stator Cascade","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mechanisms of Secondary Flows and Losses within a Three Dimensional Turbine Stator Cascade","subitem_title_language":"en"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45229","relation_version_is_last":true,"title":["Mechanisms of Secondary Flows and Losses within a Three Dimensional Turbine Stator Cascade"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:43:00.361558+00:00"}
