In the DNS, a jet is forced by random disturbances and a pair of unstable helical modes. The linear stability analyses indicate that decrease of the shear layer thickness increase the growth rate of the helical modes and increase the azimuthal wave number of the helical modes with subsonic phase velocity. Also, the DNS results show that although the radiated Mach waves are reduced as the azimuthal wave number of the added helical modes pair increase, the jet potential core region gets elongated. These results indicate that, in suppression the Mach wave, not only the length of the potential c ore but also the speed of the added disturbance is important.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1830029016","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-18-005","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(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"富山大学"},{"subitem_text_value":"富山大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Toyama"},{"subitem_text_language":"en","subitem_text_value":"University of Toyama"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡辺, 大輔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"石崎, 匡則"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Daisuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishizaki, Masanori","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":"2020-01-15"}],"displaytype":"detail","filename":"AA1830029016.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830029016.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2945/files/AA1830029016.pdf"},"version_id":"319ddff0-2b09-49b9-97f5-6d3504b7896d"}]},"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":"超音速ジェットにおけるヘリカルモードペアを用いたマッハ波抑制のせん断層厚さの影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"超音速ジェットにおけるヘリカルモードペアを用いたマッハ波抑制のせん断層厚さの影響"}]},"item_type_id":"5","owner":"1","path":["1531","1875","1891","1976"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-02-28"},"publish_date":"2019-02-28","publish_status":"0","recid":"2945","relation_version_is_last":true,"title":["超音速ジェットにおけるヘリカルモードペアを用いたマッハ波抑制のせん断層厚さの影響"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:13:23.705691+00:00"}
