The method consisted of an airfoil, boundary layer and eN codes, respectively. The airfoil code used the vortex singularity method and the boundary layer code Keller's Box method. In the eN code, the Orr-Sommerfeld equation was solved spatially with a given fundamental flow by the Itoh method (ref.8) and the growth rate - alphai was integrated from the neutral point to an arbitrary downstream point, which gave the total amplification of the disturbance. A transition point was predicted by the point at which the total amplification became eN. As an example of the calculation, the laminar boundary layer over the surface of the NACA 0012 airfoil with the suction velocity determined by the Michel criterion (ref.2) which could maintain the laminar flow over a full chord length was tested to confirm the very strong stabilizing effect of the suction. The result showed that both the Michel and the eN methods agree well qualitatively, but some uncertainty remains about quantitative agreement.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALSP0005017","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-5","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":"航空宇宙技術研究所"},{"subitem_text_value":"航空宇宙技術研究所"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石田, 洋治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 信毅"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishida, Yoji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ito, Nobutake","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":"nalsp0005017.pdf","filesize":[{"value":"558.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0005017.pdf","url":"https://jaxa.repo.nii.ac.jp/record/43197/files/nalsp0005017.pdf"},"version_id":"ac751955-fc1f-425c-b2f3-88aae98249dc"}]},"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":"層流制御計算におけるeN法の応用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"層流制御計算におけるeN法の応用"}]},"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":"43197","relation_version_is_last":true,"title":["層流制御計算におけるeN法の応用"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:20:34.084610+00:00"}
