However, work output must be high as possible. As a result, pressure ratio of the turbine becomes high and Mach number at both nozzle exit and rotor inlet becomes supersonic. Therefore strong shockwave interaction can be generated between nozzle exits and rotor inlet, and this interaction affects the turbine aerodynamic performance. However this rotor-stator interaction of supersonic turbine has not yet been clarified. To evaluate such numerical approach, in the present study, quasi 2D RANS simulations were applied to the NACA supersonic turbine and the numerical results were compared with the experimental results. The flow field between nozzle and rotor region and the turbine isentropic efficiency were investigated. RANS models and nozzle/rotor interface modeling method were compared, and its impact to the turbine aerodynamic performance was evaluated.","subitem_description_type":"Other"}]},"item_5_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"},{"subitem_description":"形態: CD-ROM1枚","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"},{"subitem_description":"Note: One CD-ROM","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064741013","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10324301","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構情報・計算工学センター"},{"subitem_text_value":"宇宙航空研究開発機構情報・計算工学センター"},{"subitem_text_value":"宇宙航空研究開発機構情報・計算工学センター"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"JAXA's Engineering Degital Innovation Center, Japan Aerospace Exploration Agency (JAXA)(JEDI)"},{"subitem_text_language":"en","subitem_text_value":"JAXA's Engineering Degital Innovation Center, Japan Aerospace Exploration Agency (JAXA)(JEDI)"},{"subitem_text_language":"en","subitem_text_value":"JAXA's Engineering Degital Innovation Center, Japan Aerospace Exploration Agency (JAXA)(JEDI)"}]},"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":"河津, 要"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"谷, 直樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山西, 伸宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawatsu, Kaname","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tani, Naoki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamanishi, Nobuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Rocket Engine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Supersonic Turbine","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"液体ロケットエンジン用低反動度超音速タービンにおける効率低下の数値予測技術について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"液体ロケットエンジン用低反動度超音速タービンにおける効率低下の数値予測技術について"}]},"item_type_id":"5","owner":"1","path":["1703","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"16583","relation_version_is_last":true,"title":["液体ロケットエンジン用低反動度超音速タービンにおける効率低下の数値予測技術について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T04:50:44.822759+00:00"}
