One of the channel walls is modified by introduction of the wavy wall model with the amplitude of 4 percent of the channel half height and the wave number of 1.02. The experiment is focused on the two-dimensional traveling wave instability. The results are compared with the theory proposed by Floryan. It is shown that the flow is destabilized by the wall corrugation at subcritical Reynolds numbers below 5,772, as predicted by the theory. For the present corrugation geometry, the critical Reynolds number is decreased down to about 4,000. The spatial growth rates, the disturbance wave numbers and the distribution of disturbance amplitude measured over such wavy wall also agree well with the theoretical results.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0049208025","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-05-012","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":"東京都立科学技術大学 工学部　航空宇宙システム工学科"},{"subitem_text_value":"University of Western Ontario Dept. of Mech. and Materials Engineering"},{"subitem_text_value":"東京都立科学技術大学 工学部　航空宇宙システム工学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo Metropolitan Institute of Technology Department of Aerospace Engineering, Faculty of Engineering"},{"subitem_text_language":"en","subitem_text_value":"University of Western Ontario Department of Mechanical and Materials Engineering"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Metropolitan Institute of Technology Department of Aerospace Engineering, Faculty of Engineering"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"浅井, 雅人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Floryan, J.
