The governing equations were discretized and numerically integrated using the finite volume method. The temperature dependence of thermodynamical properties was taken into account; transport properties were calculated according to the simplified transport model proposed by Smooke [Reduced Kinetic Mechanisms and Asymptotic Approximations for Methane-Air Flames, (1991), p.1-28, Springer-Verlag]. Fuel jet velocity was found to have tha same effects on the flame structure and the unsteady behavior as those concluded from the flame sheet approach ; by increasing the fuel jet velocity, the flow becomes turbulent with large fluctuations downstream, and the flame is disturbed by the enlarged fluctuations in the turbulent region downstream where local extinction takes place. From a comparison with the laminar counterflow diffusion flame, it was concluded that the hypothesis of the laminar flamelet model that “the instantaneous local structure of the turbulent flow field can be accurately simulated by the laminar diffusion flame\", can be applied to the unsteady turbulent jet flame that includes the possibility of extinction and takes into account the NOx formation process. As a result, it was verified that the formation of NOx in the turbulent flow field has the same mechanism as that in the unsteady laminar diffusion flame even for the case of extinction.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/8999"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society of  Mechanical Engineers","subitem_publisher_language":"en"}]},"item_10_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110003474321/","subitem_relation_type_select":"URI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本機械学会","subitem_rights_language":"ja"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである。","subitem_rights_language":"ja"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1340-8054","subitem_source_identifier_type":"PISSN"}]},"item_10_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"YAMASHITA, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"20163","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-19"}],"displaytype":"detail","filename":"JsMecEngB_43-1-97.pdf","filesize":[{"value":"861.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JsMecEngB_43-1-97.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/7318/files/JsMecEngB_43-1-97.pdf"},"version_id":"da558844-64b8-4fdd-958d-1cbcba7c2005"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Diffusion Combustion","subitem_subject_scheme":"Other"},{"subitem_subject":"Jet","subitem_subject_scheme":"Other"},{"subitem_subject":"Pollutant","subitem_subject_scheme":"Other"},{"subitem_subject":"Kinetics","subitem_subject_scheme":"Other"},{"subitem_subject":"Numerical Analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"CH4","subitem_subject_scheme":"Other"},{"subitem_subject":"Unsteady Behavior","subitem_subject_scheme":"Other"},{"subitem_subject":"NOx","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Numerical Study on NOx Production of Transitional Fuel Jet Diffusion Flame","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Numerical Study on NOx Production of Transitional Fuel Jet Diffusion Flame","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-11-09"},"publish_date":"2007-11-09","publish_status":"0","recid":"7318","relation_version_is_last":true,"title":["Numerical Study on NOx Production of Transitional Fuel Jet Diffusion Flame"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:52:54.030520+00:00"}
