The ignition was performed at the center or at a point on the periphery of the chamber to observe the effects of wall configuration. The mixtures selected were hydrogen-air, methane-air and propane-air with various equivalence ratios. As a result, it is found that the instabilities occur when the Lewis number of the unburned mixture is less than unity for the hydrogen-air and propane-air flames. This shows that instability is caused by the so-called \"preferential diffusive instability\". However, in the methane-air flame, for which the Lewis number is always near unity, an instability with very regular cells appears when the flame approaches the wall for any value of the equivalence ratio. This instability may be interpreted as a \"hydrodynamic instability\" affected by the presence of the wall.","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":"Ohyagi, Shigeharu"},{"subitem_text_value":"Yoshihashi, Teruo"},{"subitem_text_value":"Matsui, Jun"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A3000147"}]},"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":"1994-1"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大八木, 重治"},{"creatorName":"オオヤギ, シゲハル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉橋, 照夫"},{"creatorName":"ヨシハシ, テルオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松井, 淳"},{"creatorName":"マツイ, ジュン","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":"A3000147.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A3000147.pdf","url":"https://sucra.repo.nii.ac.jp/record/12728/files/A3000147.pdf"},"version_id":"adc1244b-590a-4d4c-af30-70ffde8b3fce"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Combustion Phenomena","subitem_subject_scheme":"Other"},{"subitem_subject":"Premixed Combustion","subitem_subject_scheme":"Other"},{"subitem_subject":"Gaseous Fuel","subitem_subject_scheme":"Other"},{"subitem_subject":"Flame Instabilities","subitem_subject_scheme":"Other"},{"subitem_subject":"Internal Combustion Engine","subitem_subject_scheme":"Other"},{"subitem_subject":"Preferential Diffusion","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":"定容容器内を伝ぱする火炎面の不安定性 : 水素-空気,メタン-空気,プロパン-空気火炎","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"定容容器内を伝ぱする火炎面の不安定性 : 水素-空気,メタン-空気,プロパン-空気火炎"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-09-11"},"publish_date":"2007-09-11","publish_status":"0","recid":"12728","relation_version_is_last":true,"title":["定容容器内を伝ぱする火炎面の不安定性 : 水素-空気,メタン-空気,プロパン-空気火炎"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:53:28.323397+00:00"}
