Since, this phenomenon is also related to a safety-engineering problem where combustible gaseous mixture is handled, a device applying a narrow channel in a pipe might be one of useful technique to prevent the flame from propagating. Experiments were conducted to investigate a behavior of the flame propagating through a narrow channel, which connects two rectangular combustion chambers. The behavior of the flame was visualized using schlieren optical technique with an aid of high-speed video camera. In this study, an equivalence ratio of methane-air mixture, initial pressure and a width of the channel were varied in order to investigate effects of these parameters on characteristics of the flame propagation. As a result, the behavior of the flame entering into the narrow channel was classified into two phenomena, i.e. (i) the flame was quenched inside the narrow channel and combustion wave was not propagated into the downstream chamber, which results in just an emission of burned gaseous jet to the downstream chamber, (ii) the flame was propagated through the channel without quenching, which produced a high-pressure at both chambers.","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":"OBARA, Tetsuro"},{"subitem_text_value":"OHYAGI, Shigeharu"},{"subitem_text_value":"NISHINA, Yusuke"},{"subitem_text_value":"NARISAWA, Nobuyuki"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A3000011"}]},"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":"Saitama University, Graduate School of Science and Engineering"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2006-08"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小原, 哲郎"},{"creatorName":"オバラ, テツロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"大八木, 重治"},{"creatorName":"オオヤギ, シゲハル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"仁科, 祐介"},{"creatorName":"ニシナ, ユウスケ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"成澤, 伸之"},{"creatorName":"ナリサワ, ノブユキ","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":"A3000011.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A3000011.pdf","url":"https://sucra.repo.nii.ac.jp/record/12622/files/A3000011.pdf"},"version_id":"06e07a77-b27e-4de4-861e-a3ed7e312339"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Combustion","subitem_subject_scheme":"Other"},{"subitem_subject":"Premixed Combustion","subitem_subject_scheme":"Other"},{"subitem_subject":"Premixed Combustion","subitem_subject_scheme":"Other"},{"subitem_subject":"Combustion Phenomena","subitem_subject_scheme":"Other"},{"subitem_subject":"Pressure Wave","subitem_subject_scheme":"Other"},{"subitem_subject":"Flow Visualization","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":"狭い間隙に進入する火炎の挙動に関する実験的研究(熱工学,内燃機関,動力など)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"狭い間隙に進入する火炎の挙動に関する実験的研究(熱工学,内燃機関,動力など)"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-07-10"},"publish_date":"2007-07-10","publish_status":"0","recid":"12622","relation_version_is_last":true,"title":["狭い間隙に進入する火炎の挙動に関する実験的研究(熱工学,内燃機関,動力など)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:57:35.068118+00:00"}
