Particularly, Quad Cities Unit 2 steam dryer experiences hig h cycle fatigue due to an acoustic-induced vibration in case of the power uprate. It is conceivable that the increased steam flow passing, resonantes among a structure, a flow and a pressure fluctuation, resulting in the breakages. To understand the basic mechanism of the resonance, previous research es were done by FEM or point measurement, while it was difficult to understand acoustic resonance in details. This study aims to understand mechanism of acoustic resonance in BWR with numerical simulation, and to compare the result with the PIV experiment data","subitem_description_type":"Abstract"}]},"item_7_select_21":{"attribute_name":"学位","attribute_value_mlt":[{"subitem_select_item":"master"}]},"item_7_text_24":{"attribute_name":"研究科・専攻","attribute_value_mlt":[{"subitem_text_value":"新領域創成科学研究科人間環境学専攻"}]},"item_7_text_27":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_text_value":"修創域第3514号"}]},"item_7_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院新領域創成科学研究科環境学研究系人間環境学専攻"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"平川, 裕雅"}],"nameIdentifiers":[{"nameIdentifier":"8988","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":"2017-05-31"}],"displaytype":"detail","filename":"K-02278-a.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨(summary)","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/3854/files/K-02278-a.pdf"},"version_id":"e6f3e298-db52-48eb-8c92-cd6d94fa6e7e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"BWR","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Steam Dryer","subitem_subject_scheme":"Other"},{"subitem_subject":"Flow-Induced Acoustic Resonance","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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"数値解析によるBWR上部プレナム内における音響共鳴現象評価（要旨）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"数値解析によるBWR上部プレナム内における音響共鳴現象評価（要旨）"}]},"item_type_id":"7","owner":"1","path":["234","256"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-10-12"},"publish_date":"2012-10-12","publish_status":"0","recid":"3854","relation_version_is_last":true,"title":["数値解析によるBWR上部プレナム内における音響共鳴現象評価（要旨）"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:45:32.161824+00:00"}
