Atomizing air velocity (or pressure difference) was varied in a range wider than the conditions of actual engines. The sauter mean diameter (SMD) decreased at approximately a 1.5 power of the atomizing air velocity, being a higher velocity index than the previously reported values of 1-1.2. It was unexpectedly found that the effect of the liquid/air flow ratio was small. Since swirling flow increased the SMD at lower air velocities yet decreased it at higher ones, it is suggested that the reverse flow near the nozzle pintle adversely affects atomization.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTM0644000","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 TM-644","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":"0452-2982","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":"AN00314334","subitem_source_identifier_type":"NCID"}]},"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熱流体力学部"},{"subitem_text_value":"東京電機大学機械工学科"},{"subitem_text_value":"東京電機大学機械工学科"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Thermofruid Dynamics Division"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Denki University, Department of mechanical Engineering"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Denki University, Department of mechanical Engineering"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"林, 茂"}],"nameIdentifiers":[{"nameIdentifier":"468455","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小糸, 淳"}],"nameIdentifiers":[{"nameIdentifier":"468456","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"菱木, 学"}],"nameIdentifiers":[{"nameIdentifier":"468457","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HAYASHI, Shigeru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"468458","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Atsushi, Koito","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"468459","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Manabu, Hishiki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"468460","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":"2020-01-29"}],"displaytype":"detail","filename":"naltm00644.pdf","filesize":[{"value":"784.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltm00644.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44227/files/naltm00644.pdf"},"version_id":"6f8a9c0b-a6e2-47c7-977e-fe8e68218fb0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Prefilming airblast atomization;  Sauter mean diameter;  SMD;  swirling flow","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"実用気流微粒化燃料ノズルの微粒化特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"実用気流微粒化燃料ノズルの微粒化特性"}]},"item_type_id":"3","owner":"1","path":["1893","1916"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44227","relation_version_is_last":true,"title":["実用気流微粒化燃料ノズルの微粒化特性"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:00:36.820362+00:00"}
