First a steady flow is obtained and then small pressure fluctuations are imposed on the flow at the nozzle inlet. It is found that the voidage waves are induced by the applied pressure fluctuations. They propagate downstream through the nozzle with the same velocity as that of the bubbles. Theoretically, voidage waves are expected to be amplified and the flow becomes unstable in the throat region where the velocity slip between the liquid and the gas bubbles is present. Numerically, however, the unstable behavior of the voidage wave was not found at least in the present numerical simulations. This might come from the fact that the artificial viscosity involved in the numerical scheme tends to suppress the amplification of unstable waves.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0014023","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 SP-14","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":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"京都大学工学部航空工学科"},{"subitem_text_value":"京都大学工学部航空工学科"},{"subitem_text_value":"京都大学工学部航空工学科"},{"subitem_text_value":"京都大学工学部資源工学科"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautics Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautics Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Aeronautics Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Mineral Science and Technology Kyoto University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石井, 隆次"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"梅田, 吉邦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森岡, 茂樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"八田, 夏夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishii, Ryuji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Umeda, Yoshikuni","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Morioka, Shigeki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hatta, Natsuo","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":"2020-01-28"}],"displaytype":"detail","filename":"nalsp0014023.pdf","filesize":[{"value":"445.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0014023.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43456/files/nalsp0014023.pdf"},"version_id":"a06106d2-4aaa-43e8-9f29-12b439dc3e2d"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"加速ノズル内気泡流の数値解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"加速ノズル内気泡流の数値解析"}]},"item_type_id":"3","owner":"1","path":["1893","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"43456","relation_version_is_last":true,"title":["加速ノズル内気泡流の数値解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:14:22.835493+00:00"}
