The two-dimensional compressible Navier-Stokes equations are solved by a 6th-order-accurate Pade type compact scheme and a 4th-order-accurate Runge-Kutta scheme. The Reynolds number based on the airfoil chord length is prescribed to be 5,000, and the Mach number of the uniform flow to be 0.2. The angle of attack is varied from 5 deg to 8 deg. The results show that dipole sounds are generated in accordance with the oscillations of lift and drag forces due to the vortex shedding. As the angle of attack varies, the flow structure near the airfoil is affected, and the generated sounds change in response to the transition of the vortex motion around the airfoil.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047776009","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-04-002","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"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東北大学流体科学研究所"},{"subitem_text_value":"東北大学 工学部　機械航空工学科"},{"subitem_text_value":"東北大学流体科学研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Fluid Science, Tohoku University"},{"subitem_text_language":"en","subitem_text_value":"Tohoku University Department of Aeronautics and Space Engineering, Faculty of Engineering"},{"subitem_text_language":"en","subitem_text_value":"Institute of Fluid Science, Tohoku University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"畠山, 望"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"入江, 智洋"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"井上, 督"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hatakeyama, Nozomu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Irie, Tomohiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inoue, Osamu","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":"2020-01-16"}],"displaytype":"detail","filename":"47776009.pdf","filesize":[{"value":"293.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"47776009.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6563/files/47776009.pdf"},"version_id":"2c696842-987d-4fbd-8a4a-413c9bc99f78"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"翼型","subitem_subject_scheme":"Other"},{"subitem_subject":"2次元モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"直接数値シミュレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"均一流","subitem_subject_scheme":"Other"},{"subitem_subject":"圧縮性流れ","subitem_subject_scheme":"Other"},{"subitem_subject":"Runge-Kutta法","subitem_subject_scheme":"Other"},{"subitem_subject":"空力音","subitem_subject_scheme":"Other"},{"subitem_subject":"Navier-Stokes方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"airfoil","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"two dimensional model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"direct numerical simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"uniform flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"compressible flow","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Runge-Kutta method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aerodynamic sound","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Navier-Stokes equation","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":"翼型による空力音の2次元直接数値計算","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"翼型による空力音の2次元直接数値計算"}]},"item_type_id":"5","owner":"1","path":["1083","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6563","relation_version_is_last":true,"title":["翼型による空力音の2次元直接数値計算"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:53:23.722970+00:00"}
