The increase of oscillation amplitude in the tube brings about the nonlinear phenomena of wave motion, such as mean pressure distribution along the tube axis, acoustic streaming, and thermoacoustic effect. The large amplitude pressure fluctuation and the thermoacoustic effect generated by finite amplitude standing wave induced in the closed tube are principal physical phenomena in the engineering applications of the finite amplitude wave motion to acoustic compressor and thermoacoustic refrigerator. In order to develop these practical systems, it is essential to realize large amplitude oscillation in the tube. However, the increase of oscillation amplitude is limited by the acoustic saturation caused by nonlinear wave distortion which steepens wave front to shock wave. In order to avoid the acoustic saturation, axi-symmetric tubes with cross-sectional area contraction toward the closed end are used. Basic characteristics of wave motion in the tubes with area change have been discussed with linear acoustic theory. Finite amplitude wave motions generated in different shape tubes have been analyzed numerically and compared with experimental results. Fundamental knowledge and estimation for the development of the acoustic compressor have been given from the results obtained.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人日本機械学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875016","subitem_source_identifier_type":"ISSN"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"KAWAHASHI, Masaaki"},{"subitem_text_value":"HOSSAIN, Anwar"},{"subitem_text_value":"HIRAHARA, Hiroyuki"},{"subitem_text_value":"KODUKA Kouji"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A3000053"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Science and Engineering, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2002-05"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"川橋, 正昭"},{"creatorName":"カワハシ, マサアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HOSSAIN, Anwar"},{"creatorName":"HOSSAIN, Anwar","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平原, 裕行"},{"creatorName":"ヒラハラ, ヒロユキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"小塚, 浩二"},{"creatorName":"コヅカ, コウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A3000053.pdf","filesize":[{"value":"553.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A3000053.pdf","url":"https://sucra.repo.nii.ac.jp/record/12645/files/A3000053.pdf"},"version_id":"f77f60e1-335c-4547-917f-6754a451f921"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Acoustic Resonance","subitem_subject_scheme":"Other"},{"subitem_subject":"Finite Amplitude Wave","subitem_subject_scheme":"Other"},{"subitem_subject":"Shockless Resonance","subitem_subject_scheme":"Other"},{"subitem_subject":"Acoustic Compressor","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"断面積が変化する軸対称閉管内の有限振幅定在波(流体工学, 流体機械)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"断面積が変化する軸対称閉管内の有限振幅定在波(流体工学, 流体機械)"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-09-10"},"publish_date":"2007-09-10","publish_status":"0","recid":"12645","relation_version_is_last":true,"title":["断面積が変化する軸対称閉管内の有限振幅定在波(流体工学, 流体機械)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:56:53.967659+00:00"}
