The linear stability analysis shows that there are A1 modes (antisymmetric modes) that the phase velocities are higher than the ambient sound speed including most unstable two dimensional one. On the other hand, the phase velocity of most unstable A1 3-D mode is less than the ambient speed of sound. The result of 2-D DNS shows that the amplification of a 2-D A1 mode generates strong Mach waves. In the 3-D DNS with A1 oblique modes that have a crucial effect of flow three-dimensionality, but without A1 2-D mode, the strong Mach waves disappear. These results suggest that early decrease of the jet centerline velocity caused by an A1 3-D mode restrained the strong Mach wave emission.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0045947017","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: NAL SP-56","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-457X","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":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"電気通信大学 大学院"},{"subitem_text_value":"電気通信大学 電気通信学部　機能機械工学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Electro-Communications Graduate School"},{"subitem_text_language":"en","subitem_text_value":"University of Electro-Communications Dept. of Mech.
